A game in which two individuals, usually two males, take handfuls of snow and shove their fists up one another's anuses. This game is frequently played inside of igloos for privacy though it is not required for play.
"Hey Austin we have a snow-day today! Wanna go build a snowman?"

With a wink, "Lets go play Frosty Fists instead!"

And fun was had by all.
