Well, we did this when I was in college – but we didn't have a name for it and we did it on Valentine's Day. Of course, we encountered the occaisional creep-sexist-pig(s) who thought we should abandon each other in favor is his/their at attentions. After all, we women couldn't possibly prefer the company of our friends on Valentine's Day to some random dude rubbing his over-cologned, sweaty groin against us at the bar. 🙄
