I played Rugby for a month (lol) and I can certainly attest that they are some wild motherfuckers. None of the drinking games were quite as grotesque as those but they were in the same ballpark, (there was an old ass boot going around that they were asking people to spit in, pour ketchup/hot sauce/pretty much anything else in, along with people splashing their own drinks in, and anyone caught drinking with their right hand or fucking up a chant had to drink it). It was all pretty wild stuff to be held in an Applebee's. (Normally it's a real bar but the team we played has Applebee's as their sponsor)
Great guys though, still hang out with them here and there.
