jacksepticeye syndrome 

When someone, usually when gaming, yells and screams at their screen. They're normally loud but doesn't have to be to class as jacksepticeye syndrome. Not to be confused with anything about loving jacksepticeye or being a fan.

My friend got jacksepticeye syndrome when I beat him in a game.
