After enjoying one's self to a meal of crawfish, the guy proceeds to finger the girl while the finger appears to be clean but are in fact still full of hot spices, resulting in a burning sensation in the girl's pussy.

The donkey punch when done correctly can provide pleasure, provide comedy, and wreak havoc at the same time. First, you must be making love in the less traditional way of the booty. Next, right before the money shot comes (no pun intended), rare back and use all of your strength to punch your lover in the back of the head. This causes a tightening of the anal canal, thus making your experience all the more pleasurable. When your lover wakes up, she wont remember a thing, but you will!
"Dude, last night I donkey punched the hell out of Mark!"
