gacking off
when a meth head spends all their money on drugs instead of going out with their friends and just sits in their room doing the 'speedy solo' for the whole weekend.
My cousin got high and gacked off so much he forgot his own name. He was like, 'I'm not me. I'm a cloud.'
My neighbor went full meth head and spent his rent money on drugs. Now he's doing the 'speedy solo' and screaming at a toaster.
My friend got so high from meth he thought his dog was a wizard. He gacked off and then tried to cast a spell on his pizza.
