You motherfucker. You think you can define Zach Attack? That hard ass motherfucker will fuck your shit into the fourteenth dimension and back. How about this. He bites into a dorito loco taco and the eighty four women closest to him orgasm so hard their vaginas start vibrating. At this point, the dopamines literally start leaking out of their ears, nose and mouth, sometimes causing asphyxiation and/or divorce.

Velma: yeah, thank heavens he does not like mexican food.
