Gack

A word used by a fucking idiotic British person who tried to create his own language while playing video games on YouTube.

Gavin of Achievement Hunter used the word 'gack' and was promptly called a fucking idiot.

gack dancer

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.
