Ghetto Flaps 

A term used by snowboarders/skiiers referring to the zippers at the ankles of your snowboard pants that zip up to make your pants tighter around your boots. Unzipped they make the pants appear baggier and therefore more "ghetto".

"Undo your ghetto flaps you look like a homo."

bandit flaps 

The flaps tailors cut in the back of suit jackets, ostensibly for ventilation, but actually to allow arse bandits easier access. Most modern jackets have either one or two bandit flaps upon them, but traditional, well cut and stylish jackets will have nothing to do with this bizarre practice.

"Look at the bandit flaps on that guy's jacket!"

2. Flaps for a cock. Not to be confused with Cock Flasps
