A sexual act by nature (fetish) the muddy duck is when one person anally penetrates another person while flapping their arms and quacking like a duck.

Steve had so much fun packing Kathy's fudge, he quacked like a muddy duck.

Muddy duck eggs 

A duck creates an egg so if "Muddy Duck" (the band) releases a single it is thier egg so instead of dropping an album they will be laying a dozen eggs. It is also a term used to describe their fans.

"Did you hear the new Muddy duck eggs"
Or
"Did you hear the new eggs muddy duck laid"
Or

Q ="Are you an egg?"

muddy butt duck walk 

This is a shameful act that only happens in desperation when you are home alone and have completely run out of toilet paper. With your pants around your ankles, squat walking, and your hands spreading the butt cheeks so you don't smear shit everywhere, you walk this way to your roommates bathroom to finish the job.

Greg had to do the muddy butt duck walk to my bathroom to get more toilet paper.

Muddy Duckskin 

When you fuck a girl in the ass so balls deep, that her shit gets all over your scrotum. You don't notice the wet shit on your sack until you look down. It's quite shocking.

Unlucky Dude: What the quack, Kacie? Your mud is all over my hairy ballsack!

Kacie: It's your own damn fault for penetrating my asshole so gosh darn deep!

Unlucky Dude: Well now I have a Muddy Duckskin...thanks a lot!!!!
