When having unprotected anal sex, upon male ejaculation into the recipient's rectum, an anus-stretched situation may occur that results in the semen dripping out of the rectum. This is known as a dirtpipe milkshake, aka anal creampie.

Alternately, if the recipient wants to, they can squeeze out the semen on command, resulting in a dirtpipe milkshake on demand.

dirtpipe = rectum
milkshake = semen
