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.

1. Peanut butter and tuna sandwiches are Mcnasty.

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

McNasty

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

Scott is such a McNasty I doubt he will get hired after his time is up!

McNasty

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.
