Slap'n'flap 

The circumstance in which your penis Is wacked around until it starts peeling. Usually an activity initiated by a couple, or more commonly done by homies.

Bro 1: dude my foreskin fell of by the time I went to bed last night.
Bro 2: the slap'n'flap I gave you left my hands calloused.

Flap Noodle 

A limp, flaccid penis. May also be used to slap and flap someone about their face or some other part of their body.

I gave my sister the flap noodle after she refused to wake up and get out of bed and come to breakfast.

Rachel sucked me off. She wanted more. I didn’t so I gave her the flap noodle and told her to go to sleep.

I drank so much I gave myself the flap noodle. I couldn’t even rub one out.

The nut cutters are really showing off my flap noodle.

My step mom walked into the bathroom and was eyeing my flap noodle in the mirror.

Flap nap 

When a person preforms cunnilingus on a woman and falls asleep halfway through, without the knowlege of the woman. The resulting snores against the vulva and labia (both mayora and minora) create a flaping action that proves to be more pleasurable for the woman than the actual intended act of cunnilingus. Unbeknownst to the woman, her partner is asleep and isn't even trying.

Woman#1: Paul is such a slob, he fell a sleep while eating me out.
Woman2: Did he atleast take a flap nap?
