gackattack
A gackattack is when a pill-popping idiot turns into a sweating, twitching, brain-burning lunatic. They dance like they’re trying to win a bet, talk nonsense, and think the music is the only thing that matters.
At the rave, my friend had a gackattack and tried to dance on the ceiling like it was a stage.
He took so many pills, he thought he was a DJ and started playing music with his feet.
She got so hot she thought she was on fire and started running around like a maniac.
