When you donkeythump someone, you fuck them in the ass and when you're about to blow your load you whack them on the back of the head so they clench. I have experience with this myself.
I donkeythump, therefore I am, although have been donkeythumped myself several times

An involuntary meeting usually intiated by your supervisor that is generally considered a waste of time. When over it generally leaves one feeling fucked up the ass without the lube.
Five minutes after my shift began my supervisor came to me to talk. I knew that I was in for a donkey thump.
