The act of watching and judging people exiting a convenience store, usually while sitting in a parked car or pumping gas out front.
"Passing the 7-11 Test" means someone who looks especially good, often inciting a double-take, swoon, or wolf-whistle (at least on the inside), among the otherwise random collection of humanity who pass through those doors.
Damn, girl! You passed the 7-11 test! Glad you were getting into MY car!
Seeing my own reflection in the store window, I had to admit, I passed the 7-11 test!
Poor girl, with those thunder thighs and muffin top, she definitely failed the 7-11 test.
