More Skank.
The accepted definition of this word-in adjectival form-according to Webster's New World College Dictionary is:
[slang] sleazy, offensive, disreputable, etc. in appearance or character.
Now, I have no problem slamming someone because of a deficiency of character-which appears to be the case with this woman-but I think that it's pretty reprehensible to launch a personal attack against someone based solely upon their appearance.
