Shart Flap

A Shart Flap is a piece of absorbent material, like bamboo cloth, sewn into the back of Commando brand shorts to prevent visibility of any shart aftermath.

Thank God my Commando shorts had a shart flap or people could see my Taco Bell accident that snuck up on me.

Flap Track

When someone is eating a mans ass in front of a dirt bike exhaust and the receiver revs the motor so their ball bag slaps the ass eaters face/chin.

I'm pretty sure I saw Tommy and Sean flap tracking in the pits last night.
