Another word for steroid abuse. This term originates from UFC Heavyweight Alistair Overeem's declaration that he "doesn't take steroids;" he "eats horse meat." This statement was in the midst of many allegations of illegal steroid abuse by the fighter after he went from a lanky kick boxer to a lean 265 lb "Demolition Man."
Person 1: Did you see how big that guy was?
Person 2: It's horse meat, bro.
