petrosexual
n.— «With the former professional wrestler Bill Goldberg as its host, “Bullrun” is the television spinoff of the real-life road rally of the same name, in which entry fees run more than $17,000. Participants, who sometimes refer to themselves as petrosexuals, take their socializing almost as seriously as their racing. (In 2004 Paris Hilton dropped the flag for Bullrun.)» —“Petrosexuals, Start Your Engines (and Your Foul Mouths)” by Susan Stewart New York Times Mar. 13, 2007. (source: Double-Tongued Dictionary)
