Is when a women fills her vagina with chocolate pudding(snack Pack) and then you fuck her. It looks as if the fudge is melting on you're dick, therefore being a melting Fudgstick.
when you are doing a girl doggy style and you're just about to "blow your load" take your penis out of her butt (make sure that there is poo on your penis). then shove your penis in her mouth and cum in it
