Bat Wings 

Unlike bats wing which is performed purposefully, Bat Wings are the spreading and sticking of ones sack to the inner thigh. Usually happens at random, in summer months and is caused by the heat and persperation from the hey-nanner-nanner region.

Guy1: Dude, what the hell are you doing down there, have you got crabs or something?
Guy2: No, sorry man just have to adjust the bat wings.

Batwing

when you stretch out your ballsack like paper, then get another man to inadvertently look at it. This is followed by the ballsack exposer calling the looker gay and kicking him in the ass twice.

Guy1: Dammit! my ass hurts like shit now!

Guy2: Well then you shouldn't have look at my batwing, Fag!

Batwing Balls

The long fold of scrotum that grows over time as a man grows older.

Example:

Sylvester: Hey honey I’m feeling a little frisky. How ‘bout we roll in the deep together?

Helga: are you fucking kidding me? How can I even fuck that limp pole when you have batwing balls the size of a shower curtain?! 🦇

Tony didn't care who he was talking to, it could have been the Queen of England, he was gonna reach down and fix himself if he was batwinging it no matter who it was.
