"That fucking ex-fatty Sarah was giving me terrible head, so I flap trapped the fuck out of her."
From the Latin 'Lacina videlicet lorum' this word refers to the thin line of pubic hair on the inner vaginal flaps that is always missed while shaving.

"So I was going down on my girl last night and damn. I just could not unsee that flapstrap."
"Girl looked like she had an upside down Jason Derulo down there!"
