Muddlebutt 

A person lacking general common sense, courtesy, and is often crude in behavior. Often seems a bit slower than those surrounding them.

"Man, my manager is such a muddlebutt. She just shoved a customer over, didn't even apologize, and seemed confused when the customer gave her a dirty look."

The action of head butting then nuzzling like a cat

Most frequently a sign of affection by Celtic men to their women.

Joe nuzzlebutted Cherie. It may have hurt her a bit. But it showed the true depths of his undying love.

Yay nuzzlebutts!

Guzzlebutt 

Guzzlebutt is a word that be used for almost anything. Seemingly a word that may seem similar to the pokemon golbat... It really isn't. It is everything but that.

Your just a guzzlebutt, there's nothing more to it.
