Yap Mufflehat 

A large and foolish hat that when affixed to a dog’s head, succeeds in embarrassing the yapping canine thereby effectively causing a cessation in barking.

I bought my nextdoor neighbors, whom we refer to as the Noisetards, a charming Yap Mufflehat for their yappiest pooch and amazingly it seems to have silenced them all!

mufflestein 

A mufflestein is a woman with a muff (vagina) so hairy that it strikes fear into the hearts of men unfortunate enough to have seen it. She is well past the point of being a simple "muffy" and most likely has a hairy asshole as well.

Random #1: That girl's a muff.
Random #2: No, man, she is THE muff. She is Mufflestein.
