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.
"Hey man, can I get a pull of that franzia?"
"Fuck yeah, but don't forget to slap the bag first."

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
