quack 

A word used instead of the word wack. Typically used inside restrictive schools, where many such words are banned.

Alternatively, it's used as an exclamation or substitute for an expletive, such as fuck, in any and all situations.

Soggy Quack 

When you're having a shower and you feel a fart coming that you know is going to sound like a duck, you turn around so the water is running down your ass so the resulting fart sounds like a soggy quack.

Dude, I just let rip a total soggy quack in the shower

Quack 

-To quack is to perform an act that displays one's stupidity, incoherence, lack of coordination, or outright inability to relate or adapt in a social setting. Derived from the sound a duck makes, more specifically the verb form for what a duck (see definitions 5,8, and 9 for "duck") does.
-To fuck up the situation for everybody.

You missed the biggest quack!
What happened?
____ ran down the hill, tripped and busted ass all over the sidewalk and fence by the tennis courts!

How was your birthday?
Fun as shit, we got fucked up then ______ quacked ridiculously by hitting the blunt BACKWARDS! He didn't even notice for like 2 seconds, then he got up and slid down the hill and lost his keys.
What a fuckin' quack

I dropped the entire pizza on the ground.
You're so quackin.
