A gackattack is when an individual who has consumed stimulants such as XTC, MDMA or speed is so affected by these drugs that they lose their shit. During a gack attack, one often does not have control of many muscle functions. Sweating tends to increase dramatically along with body temperature. A persons pupils are very large. A gackattack also directly influences ones brain and their thoughts are merely the beat of the music. Gackattacks are beautiful experiences if you love to doof, doof.

Guges: Oi cunt, last night I dropped 4 pills and I full gackattacked, it just hit me so fucking hard.
Darren: Thats fucking sick! Wish I was that gacked myself.
