The Breakfast of Champions

We get these groups of guys that come in all the time, all wearing the exact same outfits. I dunno if it’s like a a male sadie hawkins thing or what, but these dudes are head to toe fitted alike, capping it all off with identical Vans. I gotta know what the deal is. Do they all call eachother and plan this each morning? Some bff status or something? Please, fill me in on this.
