In the comments section for Amber Ambrose's Wine of the Week entry, Wine-o pointed out a possible use for the boxed wine called Seven:
Looks like I've got another contender for a good game of slap the bag...
Don't know this game? Neither did we. But Urban Dictionary does:
Slap the Bag:
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. "It's time to get drunk! SLAP THE BAG!"
Love it! Have a White Russian, Wine-o.
P.S. If you love yourself, do not look up A Serbian Film on Wikipedia after reading Bruce R's comment. Just don't.
