Pulling a Dan occurs when someone pulls a prank on someone else. When the person is pranked so badly that they cannot do anything, they tell their mother. The mother then goes to contact the mother of the pranker, with the pranker getting in trouble. Hence the term, "Pulling a Dan".
Prankee: Ah, I wish I could get revenge on that person who pranked me, but I am not clever enough. Oh, I know! I'll just Pull a Dan!
