pee-pee flap

Will: That's my pee-pee flap. It keeps my pee-pee warm and sensitive.
Angela: Hey, it's kind of cute...

fishy flapjack

After a long night of foreplay and fingerfucking, the female blue balls her partner. The next morning, the man continues to fingerfuck the female. Only this time, when he is done, he sticks his fingers in her nostrils and mouth, causing a rancid fishy stench to be stuck with her the rest of the day.

Lauren led me on like a whore last night, so this morning i gave her a fishy flapjack. She was pissed that she had to smell her meat wallet for the rest of the day.
