Bat-wings 

When both sides of your nutsack adheres to your inner-thigh.

Bat-wings are preventable by;
1. Washing your nutsack once in a while
2. Wearing tighty-whities or boxer briefs
3. Air cnditioning will stop the flow of heat and thus slow down the process of sweaty nuts.

When I wake up after a hot night/banging, I will typically wake up with bat-wings if I sleep in the buff or with loose boxers.

"Hey babe, wake up! Check this out! When I open my legs, it's like bat-wings!"

Bat-wings 

The bat-wing is the result of stretching the skin of one’s scrotum, without the testicles, forming a wrinkled, veiny and translucent flap of skin that resembles the wing of a bat.

I lowered the zipper of my pant’s fly and stretched my bat-wings out.

Bat's wings 

The withered and discoloured labia of an elderly woman.

Her old bat's wings fluttered around the root of my hampton while her dentures rattled with pleasure.
