A dump or shit.
I've got a turtle head pokin' out and it's telling me it's time to go make a dirty baby.

Banging the girl from behind with your thumb in her ass. Then you reach around and have her suck it. Also known as the "Gerber".
She knew she'd been a bad girl and would be getting the dirty baby as punishment.
