The phenomenon when a recent college graduate acts extremely douchie at a bar by pretending to be way too cool. Named after a douchie bar in a large Midwestern city.
"Hey Matt, did you see those five clowns standing in the corner of the bar acting all Mad Riverish? Those jokers graduated from college like 5 minutes ago and now they are acting like their shit don't stink. What a bunch of lame 30k millionaires."
