Dirty Rice is a term that basically means "a shit-stained pussy". It occurs mid-coitus when you pull out of the anus and proceed to insert into the vagina and continue coitus.
Your friend awakes from a daydream to declare "last nite I was banging your mom in the butt then I pulled out and put it in her vag!!" Which is then followed by an observer declaring, they call that dirty rice!!
Slop tart is a classic term for a girl who is just a flat out train wreck.
Characteristics of a slop tart include one or more of the following: muffin tops, bleach-blond hair, fat tits, fake UGGs, grimy teeth, beef curtains, tramp stamps, orange skin, heavy makeup and herpes.
This is not a girl you take out on a date, sleep with or even show remote interest in. She simply exists so you and your friends can ridicule her endlessly til she decides to find her dignity and change her repulsive ways.
Man 1: You see that girl over there?
Man 2: Yeah, what about her?
Man 1: She used to be hot, but after I dumped her she turned into a total slop tart.
Man 2: Damn, dude!
Women have this and men want to be inside this. It's a great place to visit on the weekend or just somewhere to toss your hot dog into from time to time. The tighter the better and the balder the better. And last but not least, if it smells like rotten cheese or cheap tuna, proceed with caution.
Hike up that skirt girl and lemme see that pink dugout!
