MUFF
 

So, while reading a fark boobie thread, I came across the word 'muff'. Curious, I trekked on over to urbandictionary.com and found that muff means a matte of pubic hair. Interestingly enough, it also means:

3. MUFF link send redefine 33 up, 28 down
Acronym for Mandatory Ugly Fat friend. Every hot girl has one, if you find one that doesn't have a MUFF:
1. You are a moron, look harder
2. She IS the MUFF, and youre still a moron
3. She is a succubus, the only exception to the rule, stay the hell away from her, she'll ruin your life
If you don't have a MUFF, you are one.

For convenience:

And how would a succubus ruin one's life anyways? Isn't that the holy grail, the friends-with-benefits land?

A succubus is a hot girl who pulls you in and then turns into a complete bitch. She will most definitely ruin your life.

How about I turn the tables on this beeyotch and dump her before she ruins my life :D

Best succubus breakdown ever. :)

And no, I'd never heard of "MUFF" as an acronym like that...

*waits for someone to freak out on the ugly/fat portion of it*

Interesting.
