Get the macket mug.
Portmanteau of the words Meat and bracket.

This is when two males press their erect penises against the left and right side of a female's face, thus producing the meat bracket.

If a third individual takes the front of the female's face. This is called "The Three Macketeers"
Yo, Mason, let's macket this snitch's face.
