Oh, it will.

The duck quacks at midnight.

An idiomatic phrase expressing that if something looks and acts a certain recognizable way, it probably is exactly what it appears to be.

"After the liquor store was robbed, a man was found leaving the scene carrying a gun. Did he commit the crime?"
"If it walks like a duck, looks like a duck, and quacks like a duck, it's a duck."

Mud Quack

Any noise made when you are fucking a girl in the ass.

I took the mud duck home and we decided to try anal when her asshole let out a loud mud quack.
