step on a duck

The sound of a particular fart caused by overly compressed butt cheeks. This will occur due to the person attempting to slip out a silent squeaker so as not to draw attention to his or herself. Odds are a quack-like sound will result from this expulsion. There will always be at least one person who will notice and call you out immediately.

Wow, dude! Did ya step on a duck? Nice one!

step on a duck

An extremely loud that makes your butthole explode and rumble, and when it comes out it sounds like you accidentally stepped on a duck and it screamed. Usually happens when you hold a fart until you can't hold it anymore.

Bruno: *hardly and loudly farts*
Reese: "Yo Bruno, what did ya just step on a duck?!"
Bruno: "Yeah, and it feels like my ass ripped in half."
Reese: "Pull yourself together, dude."

Did someone step on a duck?

This is something that you say when someone passes gas audibly. It refers to the similarity of a farting sound to the quacking sound made by a duck.

In some cases, this expression is used by the farter to comically deflect the embarassment. In other cases, it is used by a bystander to comically point out the fart to the general public.

What is that smell? Did someone step on a duck?
