Slap the bag

[Rihanna]

Removing the Bag of wine inside the box of wine and then passing it around, partaking of its sweet nectar as you simultaneously hold, pour, and slap the bag of wine.

[Sarah]

Alternate version of the Slap the Bag game, with the following rules:

one of the players starts the game holding the bag
other players call out a name and slap the bag; the called player must drink
the called player cannot be the player holding the bag; the bag holder is immune while holding the bag
if the caller misses the bag or is blocked from slapping the bag, they must drink instead
the player who drinks becomes the holder

[Tina]

A symbolic gesture of slapping a bag of wine before proceeding to take a pull directly from the nozzle. Usually done in attempt of asking the hangover gods for protection the next morning.

[Justin Bieber]

when a girl slaps a guys ball sack and then sucks him off (like when you slap a franzia bag and chug)

[Tina]

Discovered during a drunken discussion, Slap The Bag can also be used in conjunction with getting your dick wet. This is a term which can refer to getting your balls slapped hard by a girl....a last ditch effort to get some play.
