Something such as saying "dammit!" or "shit!" Moop is used as a term that means something negative. Or if you're just bored and feel like babbling.

Get the moop mug.
The mixture of excrement and mud on the floor of a Johnny-On-The-Spot, especially found at rainy festivals.
1. I went to the bathroom and sat my purse right in a patch of moop.
2. Under the tent at the festival, there was a stench that made us all wonder if what we were walking in was not mud, but actually moop.

Get the Moop mug.
To burp while keeping you mouth closed, then tapping your sister on the shoulder and blowing it in her face.
She wouldn't change the channel, so I burped up some pizza and mooped her.

Get the moop mug.
1. (noun): a small part or string on the end of the mop.
2. (verb): when used as a verb, this means something so terrible that nobody can even begin to explain its meaning. NEVER EVER USE MOOP AS A VERB!!!
Good example:
"Mom, most of the moops on the mop are worn out so were gonna need a new mop."

Bad example:
"I'm gonna go moop the floor!"

(Sorry if I offended anyone with that bad example, but you all must be prepared to hear it as a verb)
