head flap

A flap or roll of usually fat filled skin at the back of peoples heads revealed by baldness. Usually grows in prominence with age, weight gain, and the relentless pull of gravity.

Plural: Head Flappage

The term "head flap" came to prominence in the mid-1990's when Philadelphia teens would play a game called "Head Flap Slap Crack Trap". The game involved slapping head flaps while sticking opened packets of mayonnaise down the back of the pants. The person had to say "Head Flap Slap" and "Crack Trap" as they were doing the respective tasks in order for it count. When the prankee went to see what was in their pants they often squished the mayo into their pants which was the primary goal of the prank, the head slap being more of a diversionary tactic. This would leave a noticeable white glob that left the prankee with some embarrassed explaining to do.
"Those fools searched my body everywhere for the money but they forgot to check my head flap!"

"What is that smell?" "Gunther probably forgot to wash behind his head flap again..."

"Despite the bitter chill, the back of Walters' head remained comfortably warm due to his impressive head flappage."

The American-Indian T.P. Flap Theory

There has been much said about men and women and their respective dating strategies. Much of the ‘rules’ about these gender interactions have been debated and discussed for years. When does a person slip out of that ‘potential mate’ category and into the friend-zone?This theory proposes that it is less about time, and more about the dimensions that surround the particular relationship that dictates this.

One must first imagine an American-Indian T.P or tent pole that was first used in the mid-18th century and is still being used today. It can be closed by closing the flap and this flap can be held open to allow for easy entry and exit into the tent. If one were to apply this picture to a relationship between a man and a woman, it will allow for the theory to be understood. The theory says that when the flap is open, the relationship still has potential to turn into a romantic one. However, once this flap is closed and the time has elapsed, the relationship enters the friend-zone as referred to earlier and it remains this way. The potential for any further romantic activity or feelings has diminished.

The reasons for the closing of the flap are specific to the relationship. Examples could be lack of common ground, lack of sexual attraction, an immobile man not ‘making the move’ and a host of others.
