"Team Social" Whenever a player kicks a home run his/her team is invited out to 2nd base for a celebratory 'meeting.'
"Dispute Chug-Off" This is called whenever there is a play that is determined 'too close to call' by the SloshBall Commissioner. Only The Commissioner can authorize a Dispute Chug-Off.
"Slosh-Hole" This is usually a first-timer who hasn't been properly coached by his friends and proceeds to show up at SloshBall, drink WAY too much and then think he's playing in some sort of SloshBall World Series. He takes the game far too seriously, generally trying to ruin the day.
"Keg-Stand" Undoubtedly at some point in the game a keg-stand will take place. A team rallies around one of their players and props the person's body upside down above the keg, all the while filling their mouth with beer. It goes against the laws of gravity, but SloshBall players aren't known for their smarts.
