A McNasty is a delicious combination of a McChicken and a McDouble. To make a McNasty, order a McChicken and a McDouble, take the top bun off the McDouble and the bottom bun off the McChicken. Place the McChicken on top of the McDouble and enjoy!
"What are you going to get from McDonalds?" "I can't decide between a McDouble and a McChicken, I think I'm going to have to go with a McNasty."

Something so disgusting that it challenges the nastiness of any food originating from McDonalds, whether it be actual food or just something really gross.

Two McDoubles surrounding a McChicken. estimated around 10,000 cal. thats about 5 days worth of calories but its 100% greasy goodness. Also called the McGangbang because it looks like two black patties surrounding a white one

An extremely rancid, bloated, overweight and unkempt person--especially one who has the odor of decayed feces even after exhaustive bathing.

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.
