The tasteful act of receiving oral pleasure while sitting on a toilet inside a McDonalds restaurant.

A McBlumpkin is the same as a Blumpkin, except your eating a cheeseburger at the same time. So your dropping the duece, receiving fellatio, and eating a Big Mac at the same time.

Last night as McDonalds, the fry-flipper invited me in the back for a McBlumpkin.

I almost regret eating that quarter-pounder, but at least I got a McBlumpkin out of it.

McBlumpkin Decker 

When you get a blumpkin while leaving an upper decker in the rest room of the golden arches.

Get theirs to go... They've been in the bathroom long enough to leave a McBlumpkin Decker.
