Sketchy randos, on Facebook

"When Liana Roux, a junior at the University of North Carolina at Chapel Hill, was reading a Facebook event page for her friend’s birthday party recently, she noticed a terse proviso at the end of the announcement: “No randos.” The friend wanted only people she knew to come to her party and thus sought to bar any random strangers, or randos, in collegiate parlance."
