The McGasm is an intricate and delicious specimen of American food. It includes a McDonalds double cheeseburger in-between a Krispy Kreme doughnut. You have to be in good physical health to attempt eating one.

Tony-Holy shit, what was he thinking?

A special type of orgasm involving a Mc Donalds food dish and mass pleasure.
