Snarky term used at the Burningman festival which is held in the arid Black Rock Desert of Nevada where daytime temperatures often exceed 100F. The term specifically refers to a female who actively seeks and selects a male companion at the week-long festival primarily because he occupies an air-conditioned RV or trailer. The term entered popular usage in 2009, and appeared on t-shirts at the festival in 2010.
