fast flap

That piece of extra skin that hangs down from a domestic or wild cat's belly. Some say it is to help the cat run faster. This loose flap of skin on the abdomen helps the cat stretch out further with each stride. Some say it is extra skin in case the cat has to binge eat and store extra fat in the wild.

The bengal's fast flap helps it run faster, up to 30 miles per hour.

flapping chuckie

Named after Chuckie from the rugrats, the flapping chuckie is when a male with red hair whips his dick out and in an up and down motion flaps his dick about making a slapping noise from taint to belly.

I came around the corner and Eric had his pants down doing the flapping chuckie, more cock then I wanted to see in one day.

Knacker Flap

A Knacker Flap is the large flap of skin prevailing from the gut that hangs over a males genitals, making them completely invisible when naked. The sighting of a Knacker Flap usually occurs in older obese men, and is usually tucked into their shirt. It is the male version of the "gunt" which is that of a female Knacker Flap.

Holy shit, that dude's got a mean Knacker Flap!

Omg is that guy naked? Where's his privates? Oh they're underneath his Knacker Flap.

Brandy Flaps

When a girl is too drunk to have sex- the equivalent of whiskey dick/brewer's droop for men

Eyup pal, I managed to get Brenda back to my place after the club on Saturday but she was so bladdered she had brandy flaps from the off. I had to settle for a sloppy blowie instead.
