The act of walking back from an ice cream machine while you use the ice creamcone as a dick and make it look like you're groping it back and forth while you moan.
Sean was doing an ice cream masturbation while Mr. Hammer watched and smiled.
When doing anal with a female, the female would proceed to shit on the male's dick while the male ejaculates all over the shit, mixing together, to create an ice cream sandwich. The male will then force the female to eat the "Ice Cream Sandwich" in hopes of trying to seduce her.
