Once upon a time, long, long ago people had a different way of dealing with scumbags, thieves, rats, & other various undesirable people. They would be surrounded and "taught" the meaning of justice or revenge. This surrounding and the accompanying "lesson" was called the "MUCKLERS CIRCLE".
1. Similar to motor-mouth; Someone who talks excessively to no end and about many things at once.
2. Having a crooked or eccentrically shaped mouth that is seemingly rubber-like.
"She was sort of muckle-mouthed. I mean when she was talking and she got excited about something, her mouth sort of went in about 50 directions, her lips and all."
-Holden Caulfield of Catcher in the Rye
The definition of muckleboob is big idiot. The word itself is defined by combining Muckle which is an ancient scottish word meaning "Large amount" and boob, which is a dullard, oaf, or useless person. It can also be used to describe a disasterous outcome.
This is a play on two words. "Muck" and "Makeover." A makeover where everything is slathered on in a great rush.
Basically it is a makeover, but done in such a tremendous hurry or with little regard to finesse because of limited time where the one being made over may not be at all appealing to most, but is just fine for someone desperate for a date or will take anyone of the opposite sex as they are.
"Janice, Horchester is going to be here in an hour for the dance !"
"Oh my god, I look awful, what will I do ?"
"Don't worry, we'll give you a muckover. You'll be fine."
