Machine Gun Typing
When you type like a madman on a keyboard, stopping every few seconds like you're taking a smoke break from your own brain. Sounds like a machine gun, which is just a keyboard with a temper.
"BRB I'm gonna text my ex", then 10 minutes later, they're still typing like they're in a race against time.
"I'm not lazy, I'm just strategically taking breaks.", said no one ever.
Typing "I love you" 17 times in a row because they're dramatic and have no life.
