fumb ducker 

Dumb Fucker, switch the first word of each and you get Fumb Ducker. It's at least 75% more comical than calling someone a dumb fucker. You might get some wierd looks though, but only by people who are too dumb to know what you are saying.

Did you just tell Mr. Olympia that he looked queer? You fumb ducker.

Fumb duck 

When you sing all the instruments in a song, while throwing your hair in a swirlie.

Hey, remember Step Back in Time?
Oh yeah, didn't we--
What did we do?
Oh yeah, we Fumb Ducked!
Like all the time.
Every night.
Damn, we were loud.
