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

Ex. Combining a Mc Chicken with a double Cheeseburger = a Mcgasm in your mouth.

Steve: hey man are you OK? You've been chewing that chunk of your Big Mac for five minutes now.

Bob: *swallows* Yea I'm fine its just that big mac.... its so good it was causing multiple Mcgasms in my mouth.
