Two or more sorority girls in a Jeep. Typically the sorority girls are inebriated and listening to loud, usually banal, popular music.
Dick: “What are you guys up to tonight?”
George: “Probably get some beers on University Blvd. and watch for Sheep in a Jeep.”
Dick: “Jeep sheep are hot.”
Bro, you gotta be careful crossing 4th avenue on Thursday nights; Lil Wayne + Lynchburg Lemonade + Sheep in a Jeep = certain death.
