wank flapper

Someone with terrible opinions who just won't shut up about them.

Elon Musk is such a wank flapper. He's posting a bunch of tweets about how corporations are people and unions are bad again.

PhD Flopper

A perk in CoD zombies, black ops 1 and 2 to be more precise, that not only REMOVED all splash damage and explosive damage you receive, but it also makes the zombies explode when you dolphin dive near them! You may take some fall damage, but it’s a great perk!
PhD Flopper appeared on Ascension, Shangri-La, Call of The Dead, Moon, Buried, and Origins. This perk was great for only 2000 points! That’s less than Jugger-Nog!

Sadly, from Black ops 3 and so on, the games were now running on the slide mechanics, therefore PhD Flopper was removed from the franchise, and replaced with Widow’s Wine. There WAS a perk called PhD Slider, but it was just meh.

Mr. Flapper

A very loose vagina (or vagina lips). And when anal fucked, the vagina lips flap with every thrust.

I like to call my pussy Mr. Flapper
