posin' for a hosin'
At some universities, the custom of some young women to sunbathe where the football team will run by them (like beside the path between the field and the fieldhouse). The perfect posin' for a hosin' outfit is a very small thong bikini that's at least partly transparent. Easy to spot as they're the only people you've ever seen sunbathing with their makeup and hair perfect.
Your luck gets a lot better at the postgame party if you've been posin' for a hosin' all week.
