Duct Butter

The guncky build-up underneath the flap of skin on an un-cercumcized cock.

Girl: That boy got duct butter in my vagina.

duct butter

The shit that pours out of a broads pussy after your done fucking her. A mixture of her pussy juice and your cum

Man, after I finshed fucking this bitch she left Duct Butter all over my back seat.
