Back Flap

The roll of fat that forms on the back of a middle aged friend. This object is usually a surprise if you have not seen the guy in a number of years. The flab tends to look like a "flap", that if opened, might have the ability to absorb a double cheesburger (much like the Venus Flytrap). Although embarrassed, the friend knows that since he has "given up", no possibility for losing the flap exists.

Woah, Dude! Put your shirt back on...your Back Flap is freaking me out.

Hey Hans, does your Back Flap need a bra.

Buddy, what happened to you? You are sportin' a Back Flap?

A skid-mark or stain on the gusset of underwear, either as a result of not wiping properly or an ill timed fart.

Backflash 

When a woman randomly remembers a position preferably in doggy, that gives her vagina pulsations/heartbeats thus craving to relive the moment immediately.

"I just had a backflash, you mean flashback?" Usually taking place after an intense sexual act or session that the woman remembers vividly and relives or wants to repeat
