This is when a male picks up a female at a fast food restaurant like MacDonald's. Usually there are other disturbing things involved with the incident.
The other day my friend went to MacDonald's for some post drinking treats and he got a McNASTY to go...hold the fries.

A female that has taken disgust and grime to an extremity, a true whore at heart that reminds every man of something that can be purchased at mcdonalds; fat, sloppy, and down right disgusting. Generally, if you are indeed dealing with a true McNasty on your hands, chances are that she is so loose that a football can get inserted with zero difficulty.
Guy 1: Wow bro, every time I turn around that girl is hooking up with a new guy. I can't believe you got with her!

Guy 2: I know dude! Chances are I might have an STD...Im pissed.

Guy 1: Yeah dude I'd get checked out tomorrow, what a god damn McNasty

Ordering a McDouble and a McChicken, then putting both patties between one set of buns, to create one nasty sandwich.
After the bar last night, I went and got a McNasty and 10 piece McNuggets.

When a guy nails a chick in the ass and then she sucks his cock.
Guy 1: Dude, did you really give her a McNasty?

Guy 2: Hell yeah!
