Blurry

From Frikipedia

Beer slurry.

Occurs when one's drink is left in the freeze or the snowbank for too long. The level of blurriness is dependent on interaction of three factors: time, temperature, and alcoholic content (known as "the 3 T's").

In the Great White North, when traveling between establishments for an evening, blurries are a common result from leaving one's half-consumed beverage in a quiet snowbank with a slight covering of fresh powdery snow to conceal it from other squirrels. If the evening has progressed well, the blurriness will not impede further enjoyment, even many hours later.

Blurries are also common after a game of pond hockey, when the after-game beers have been left in the cold for much too long.
