Thack 

adj. 1 Term to describe a girl who is beyond thick, well into the fat range.
1a But has so damn many endearing qualities that you would never say this word to her. (conditional)
2 An insult to a female who is fat and annoying, but mostly tries to come off as sexier than she is.
3 As used in court when your ass is soundly beat by said girl, in a descriptive way, as to relate to the events of your mauling, not court opinion. Which may be the same as 2.

1 <i>(while watching t.v.)</i> "hey she is kinda cute, kinda thick." <i>(reply)</i> "Nah, she aint thick, she's thack"
