Donkey punch is a slang term for an apocryphal and potentially lethal[1] sexual practice supposedly performed during anal sex. The purported practice involves the penetrating partner punching the receiving partner in the back of the head or neck (what is known in boxing as a rabbit punch, after a technique to kill rabbits), which allegedly--although medical data shows that it doesn't even work--causes the receiving partner's anal passage to tense up and increase the pleasure of the penetrating partner.[2] When used, the donkey punch is almost exclusively executed during or just before the orgasm of the penetrating partner.[3]
