This is when a man (or sometimes woman) is bent over giving the man a blow job. While this is occurring the man/woman giving the blowjob is shitting. Simultaneously, the man receiving the blow job vomits down into the man/woman's ass crack causing a flood of vomit and shit to be flung from the anus.
*Someone who i well verse in being the bent over participant can suck vomit into the anus and then spray it out in a plethora of directions.
Ex. a man recieveing a bj vomits into the ass of the man or woman who is giving it while he or she shits, making her a Rumpelstiltskin
Noun or verb. The Rumplestilskin is a variant of the blumpkin in which a stranger initiates the blowjob while the target is on the toilet, and will continue to perform fellatio until his name is guessed. Named after the fabled trickster who would be promised a first-born child if his name could not be guessed.
John sure has been in the bathroom a long time. I hope he wasn't ambushed by a Rumplestilskin! He's a horrible guesser.
