It is where the labia of the woman is chubby and sagging in nature, also covered in a thin bristle and layer of wet slime, reminiscent of Jabba the Hutt.
A person (generally female) who's constant propensity to be a bitch is exasperated by the fact that she is morbidly obese. The massive proportion of both her cuntiness and adipose tissue warrant the title. A Jaba the Cunt's life is both defined and punctuated by the fact that she's nothing more than a fat, egocentric, boorish bitch.
Boy: Man, Paula is such a fat fucking bitch. Stupid cunt thinks she knows and owns everything.
Girl: Yeah! She's got more rolls than a pastry shop, she's a total Jaba the Cunt!
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
