An unreliable person. Someone who shows up late, doesn't pay rent or repay loans, can't hold down a job for very long, etc. Your typical moop has tattoos, piercings, court-ordered child support, a substance abuse problem and a petty criminal record. One step up from a rubadub.
I thought tending bar would be a fun job, but I couldn't stand listening to the moops tell their stupid fishing stories all day!

Moop - When u attempt to drink a half gallon of milk and get sick. Then you run and go to the bathroom and "moop"
moop looks like runny white poop (liquid out of your anus)
MOOP = milk and poop

I bet Michalak that he couldn't drink a half gallon of milk and then he mooped all over the place and his grandparents heard it.

Term used as slang in some parts of Great Britain. "Moops" or a "Moop" originated from a comical act in many northern industrial towns. Later used to express group of comical or crazy people in jest.

In addition to the thorough definition provided by CK Washington I would like to divulge the origin of the word "moop." One day a girl went on a sympathy date with a guy from work who looked like an older and more roly-poly version of the kid from Jerry McGuire. I kid you not. The boy was from Danbury and therefore came across as a complete sketchball to the girl's friends (a very logical assumption.) Being great pals, the girl's friends called her during her date. Rather than hearing the usual ringtone through the cell phone that one expects when placing a call, the girls instead could hear the following faint interjection: "moop!" Obviously they interpreted this as a cry for help from their friend to save her from the visual and verbal rapage she was suffering through during which the boy undressed her with his eyes and serenaded her with very bad, off-key Clay Aiken songs. Henceforth, "moop" became a staple of the poons' ever expanding vocabulary. And although they don't appreciate moopage from outside sources they thoroughly enjoy mooping each other. Holler pUnit!
The 11th Lost Commandment: Thou shalt not moop any member of the pUnit. Unfortunately there are many grease monkeys, grundle munchers and stumble bums out there who do not abide by this sacred law. But don't worry... they are going to hell.
