Dune Rat 

Is a slutty girl that goes to the dunes to ride quads or motorcycles with a group of guy friends. Instead of riding she likes to go behind the bushes, in the toyhauler or even the bathroom and get her insides poked by any guy in the group.

Pretends that she is there to ride and instead gets every hole in her body poked by any available cock in the group.

Easily found lurking at any Trailer Park in Indian Springs, NV.

Was out at Dumont Saturday and Met this "dune rat". I took her into bathroom 7 and gave her some sandy doggystyle while i was stuffing her head in the toilet. I couldnt even go back to the guys and brag because the whole group had already gave this "dune rat" a Dirty Sanchez

smashed rat 

When a female moons you by bending over so far that she presses her vag against a window, as in a car window. The image of a hairy vulva and red/pink labia looks like a smashed animal.

Guy: the other night after the party I mooned a car full of girls, then one of them responded and pulled a smashed rat on us.

Swamp rat 

A large city resident who, due to smog pollution and over population, has mutated into rat-like behavior. Characteristics include: erratic driving, minuet patience, extreme cynicism, narcissism, ultra materialism, competitive without competition and shallow friendliness.

When driving on the freeway in the Los Angeles area, you easily spot a swamp rat, he's the guy in the BMW swerving in and out of lanes, tail gating or waiting until the last possible moment to merge so that he can get a whopping ten feet further in stop and go traffic.
