Clam Flap

because its the flappiest part of the vagina it is the optimal spot for a raspberry: when one presses their lips against the labia majora and blows air making a sloppy wet sound.

Me: hey Chris, I clam flapped your wife last night...
Chris: "oh yeah, I was gonna clam flap her last night too but she was on her rag. BURN!"

Much to his surprise and horror when he got done licking there, there was some under flap stuck in his teeth
