Vaginal lips that are clearly visible through pants. Particularly lips that are hanging on bloth sides of the seam. Also referred to as camel toe or moose knuckles (the larger of the two varieties.)

When a woman has unusually long but fairly narrow and fishy smelling labia minora. Not unlike the adipose flap of a golden tilefish.
Man, I went to go down on this girl last night and she had a scupper flap. The appearance didn’t bother me but the smell ruined the moment.

When you squat until your labia are submerged in a bowl, cup (from KFC or Wendy’s), or barrel (for the flap dunkin connoisseurs) of mashed potatoes.
Jessica M. filled her step dad’s pool with mashed potatoes so the entire town can partake in the Dunkin’ Flaps party.
I woke up this morning to the lovely scent of garlic mashed potatoes in the air. You can imagine my disappointment when I came down to see Jessica squatting on the kitchen table, dunkin flaps.

A penis flap is the pouchy thing on your sweatshirt or backpack. Penis flaps enjoy being stroked and having sex. =)
