Diary Mode is the main running gag of the show Grojband. It involves Corey and the others needing Trina to write in her diary so that they can get some lyrics for a song, so they do something to anger her so that she writes in her diary so that they can put her diary entry into lyrics for a song.
According to Corey, the band can't come up with any good lyrics when they're writing songs. So, they steal Trina's diary and use her diary entries as an inspiration for lyrics. Trina uses her diary to express her emotions and the band finds her entries very profound and well worded which helps Corey write profound and well worded songs. However, in order for Trina to write something in her diary she must go into Diary Mode in which she must be in a extremely emotional phase (mostly anger). Corey and the band have to cause her to go into this phase by controlling the environment around her and staging her into it, which will play with her emotions. Once her intended feeling has been forced into her enough, she will blast up into the air expressing an extremely exaggerated form of her emotion. Her pen and diary will surround her and she will grab them and write in her diary while music plays to match her emotion. While she writes in her diary, a strange phenomenon will happen which will match her emotion. After she writes in her diary and gets back on the ground, Corey grabs her diary and puts her entry into words for their next song. It is unknown if Trina is aware of her diary modes as she she seems to forget them immediately after they happen. It would seem likely that she is oblivious to her diary modes as she also tends not to notice that Corey is stealing her diary and putting it into lyrics for their songs. The reason for this is that Grojband does a good job at changing it around so that you won't be able to tell that it came from her diary unless you deliberately try. This was revealed in the episode "Space Jammin'" where The Newmans tried to level with Grojband by using Trina's diary for lyrics and they read the lyrics directly from her diary which she noticed. It was explained that it was Corey's genius that puts her words into lyrics and subtlety covers it up.
When Trina goes into Diary mode, there is a set-up plot behind it. In some episodes it changes but in the majority of the episodes, it stays the same. Here is every single detail about the beginning, middle, and end of her normal, average, everyday, diary mode. It all starts with something agitating Trina a whole bunch. This will almost always be caused by Grojband because they want her do write some lyrics. Grojband will set something up that will happen to her, putting her into a state of rage. She will make an angered reaction which involves a scowl and her clenching her fists and locking them downward, she will begin shaking and music will play in the background which are satanist bells and a chorus of people singing in a haunting nightmareish tune. A lot of the times her pupils will glow red and her hair will start waving upward and she will growl in rage and sometimes you can even hear the noises of a kettle getting all steamed up. Sometimes it only contains some of these features and sometimes none, but every single time she does it, it begins with the music and her shooting up into the air on a geyser of flames and/or lava. In the middle of her Diary modes she is flying up in the air with a red background behind her and the sounds of heavy metal and screaming people as the background music. Her face is angry and has red eyes and her hair is flying in the air. She then flies up offscreen and comes back down in the distance. Objects related to the thing that's bothering her or the environment around her will come up and spin around her. Then she turns into a black shadow where only the red glare from her angry evil eyes are seen and she sticks out her fists and spins around once and then she bends over and stands back on up launching her up into the air on a black trail of shadow which the spinning things follow. Then she goes down to a place in the middle of the screen without her shadow colors or the things spinning around her but still containing her fist position, and her pen and diary spin around her and stop right by her fists. The screen changes to two screens, one showing the pen, and one showing the diary. Trina's fists go out and grab them both causing a background of red shock going behind them as she grabs them. She always grabs her pen first but just about a split second before. It will show a view of her at an angle and she will slide her pen across her diary twice and leave trails of fire on there. Then it will show the world around her and show chaos happening being caused by her words being written in there. Mostly it will be more geysers of lava and/or fire just like the one she entered on blasting out of places or it will show storm clouds forming in the skies and lightning striking in places. Then it will show a front view of her and have her pen writing slowly across the diary and fire will be seen forming around there. Then it will show her hand hold out the pen and it will be pointed upward and there will be a small flame on it that will die out and turn to smoke which will die out soon after that. Then it will pan down her arm and go to her face and her angered face of fury and rage will divert to a confused face and the red in her eyes will fade back to the normal colors. Then she will fall down offscreen and it will show a place on the ground where she lands. When she does land, the music will stop playing and the pen and diary in her hands will not be there. The diary will either land in Corey's hand as he catches it or it will land somewhere else and Corey will go out and get it. Whenever it lands you hear an angel chorus singing and after it is done Corey will mostly say a catchphrase which is "Showtime". This will have the lyrics for their song in it and the song that they play in the episode you can easily picture how the stuff in her diary would make sense as a response as to what sent her into said diary mode.

Although Diary Mode is always out of rage and involves writing fire, red backgrounds, and screaming music. There have been many times where Diary Mode has changed. Here are some of them all.
- Anger - Anger is what Diary Mode mainly and usually and almost always is. It starts with bell music playing and Trina blasts off in the air on a geyser of fire. She flies up in a red background and has red in her eyes and an angry face. She grabs her pen and diary and writes her feelings into there and flames form on the paper where she writes it. When she writes, horrible things happen to the area around her, which are mostly a bunch of fire geysers just like the one that she shoots up on. Once she's done, Her face is like "What the heck just happened?" and she falls back and ends Diary Mode. Screaming Demons and Heavy Metal Rock Music plays in the background.
- Love - Sometimes, Trina will go into a love version of Diary Mode. This happened first in the episode "Pox N Roll" Trina had Diary Mode only with love instead of anger.

There were a bunch of hearts flying around in the area she was in, The music in the background was pinao music and a huge orchestra playing the same beats as the sound that plays when she's about to go into diary mode in all of those anger times. This was also the music that was playing before she shot up into the sky.
