Refers to that "one" redneck girl that's always in the bar, wearing a Dale Jr tank top, and no bra (even though she really needs one) that randomly raises her budweiser and yells WOOHOO for no apparent reason.
"Dude, no matter how much I drink tonight, do NOT let me leave this bar with the Jr. Ho, promise me!"
