After sex when the dong is between flaccid and hard, still wet with vaginal secretions, the dong is slung across the female's face, making a "flop" sound.
I dong flopped Veronica right under her nose so she could smell it all day!
A shit mustache left behind from eating ass.
My wife noticed that I came home from work with a Dirty SÃ nchez. She was pissed because I don't eat her ass.
