Get the gackney mug.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.
