Machine Gun Typing
When you type like you're trying to break the keyboard, but you keep pausing like you're waiting for someone to answer before you go full chaos.
"YOLO", then 5 minutes of typing like they're typing a novel in the middle of a test.
Typing "I'm fine" 20 times in a row because they're lying and also dramatic.
Typing like they're in a competition, but the only prize is their own confusion.
