Here's a family favorite, but I'll warn you a head of time that it'll sneak up on you.
We call it "Can's".
You'll need
: a metal coffee Can, with a lid.
: a tea towel
: clear booze (vodka, or white rum, or whatever)
: a can of frozen juice (you'll need a bunch eventually)
: icing sugar
: fresh mint leaves
: bags of ice cubes
Take a few of the mint leaves and twist 'em up to release the oil, and then rub them
all over inside the coffee Can (removes the aluminum and coffee taste), then just
throw the leaves in the bottom of the can and dump in a whole can of frozen fruit juice
(or pink ice tea, or whatever...), add an equal amount of booze (using the empty juice
can), fill the coffee Can with ice, and a heaping table spoon of icing sugar.
Now here comes the rules. I didn't make them up, but simply follow them. Put the lid
on the coffee can and wrap the tea towel around the can. Holding the ends of the can
wrapped in the towel, shake the can until frost forms on the can and the tea towel
sticks to it. Guys have to shake the can in from of them and women have to shake the
can above their heads. Open the lid and drink, and pass the "Can." The Can cannot be
set down by anyone and has to be passed to someone who drinks and passes the Can.
Whomever finishes the Can, makes the next one...and whomever finishes that one
makes the next one...and so on and so forth. The Can will frost up when shaken within
a minute or so whether it's -15c or +40c. Trust me, it happens. At big gatherings, there
might be two or three Cans floating around at the same time.
