gacking

When your cat gets a random huge energy burst and runs around the house jumping on stuff and knocking things over like a little shit head.

I didn't get much sleep cause my cat was gacking all night.

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...
