I guess it truly is Bro Day, Snacktime.
Definition provided by Bros Icing Bros:
A new drinking game is spreading around college campuses. Quite simply the simplest, funniest drinking game ever created. It’s quite easy. Buy Smirnoff ice, present it to one of your bro’s in any manner, your bro must instantly get on one knee and chug the Smirnoff ice on the spot regardless of setting.
Now profiled even in The Times:
The premise of the game is simple: hand a friend a sugary Smirnoff Ice malt beverage and he (most participants have been men) has to drink it on one knee, all at once — unless he is carrying a bottle himself, in which case the attacker must drink both bottles of what Mr. Rospos described as a “pretty terrible” drink.
And coming soon to a youth near you.
