Alabama Popemobile

The act of having anal or vaginal sex with a man that is operating a motor vehicle at highway speeds wherein the passenger straddles the driver reverse-cowgirl style so that they have to put their hands on the ceiling to steady themselves and, in doing so, look like a waving pope. This is all done while listening to Classic Southern Rock, preferably Lynrd Skynryd.

"I was on a long road trip with my girlfriend and she got really horny so I set the cruise control on a long stretch of highway and gave here the Alabama Popemobile.
