The act of the male and the female. The male sharts on a girls hand when it is in the shape of the a curled fist. She then gives the male a handjob resulting in the male sperming on the shart covered hand, therefor resembling a cinnabun. At which point she in enjoys her free sloppy cinnabun.
Hey yo bitch, im gunna give you a sloppy cinnabun!
