Vegetarians who haven’t eaten meat for a long time become used to it and their bodies can’t handle meat the same way. So, if, by accident or on purpose, this person eats meat they will, more than likely, become sick, having been given a meat mickey.
a couple at a mexican restaurant:
person #1: i dont feel so good after that vegetarian taco.
person #2: most mexican foods use beans with LARD in them.
person #1: ugh, a meat mickey, damnit...
