To grab any shit, get it grounded, fashion into a burger and make burgers out if it.
Vegans burgerize everything.
They grab lentils, grind them, and make burgers with that shit.
A violent criminal act that entails turning someone, usually an enemy, into a "chopped" and unrecognizable non-human state that highly resembles ground meat, or a hamburger. This can be accomplished via chainsaw, rocket launcher (e.g. DOOM), meat grinder (e.g You Can't Do That on Television), or placement of said enemy in the compactor of a large sanitation department vehicle.
Mainly used, however, as a description of how badly you are going to fuck someone up, usually in a preliminarily threatening way.
