Mouthpiece 

The point at which a man's dick meets his balls.

"Shut up and put your lips on my mouthpiece, bitch"

"My mouthpiece is going to be the smartest thing that ever comes out your mouth, bitch"

Mouthpiece 

A person who chimes in or adds comments into a conversation that they are not in. A person who runs their mouth when they shouldn’t be.

Nobody asked for your opinion stop being such a mouthpiece.
