Gack Off 

Term used to describe when a meth user decides that rather than party with their friends famy and neighbors all weekend, they are going to just irresponsibly spend half their rent money on some dope and go hide out alone in their home and get higher than fuck all weekend...like a speed-driven "METHodical masturbation" type of high...

Bro, I'm so tired of smoking all my dope with these jank-ass chicks around the hood all weekend just to end up not getting any, yet still outta dope by Monday morning....fuck it, time to disappear for a couple days and gack off with my bad self...

Someone so high on meth they move uncontrollably. This usually includes wildly exaggerated leg ,hip, arm and butt movement that often look like their moving to some unknown beat and looks like very much like the dance the Elaine character on Sinefeld does.

I can't be around her when she tweeks , she turns into a gack dancer moving all crazy like that.
