Desert Rat 

A desert rat is somebody usually from the LA area that goes to raves in the desert. These people may begin this lifestyle as normal people, but soon become clones of each other. They do a wide variety of psychedelic and empathogenic drugs, and often profess their love for colors and life on Instagram and other social media. The desert rat takes on the persons of the 1960s hippie, but without the world views and political beliefs that helped build the hippie culture. To simplify, picture the body and persona of a hippie fused with the materialism and fakeness of a 21st century SoCal raver, and you have the desert rat.

The desert rat kept gushing over how far away from society their last event was, yet the whole time everyone was on their phones posting pictures to social media in order to obtain likes.

Sand Rat

One who posses extreme and uncontrollable anger and is most likely to act it out, violently. Mostly while playing games like Call of Duty where he gets killed so many times by the same "Camper Cunt" that he screams, thus either turning his Xbox off or switching to another game that he knows he will also rage on.

Josh: "AHH PANIC KNIFE!! ONE AWAY FROM MY FUCKING BLACKBIRD!!"

Assorted Xbox Party Members: "Josh stop being such a Sand Rat goddammit"
