Why does this happen?

[Wheezer]

I have frozen many a beer in my time accidentally, but they usually feeze and explode in the freezer.

Why does tapping these after pulling them from the freezer cause a reaction?

I am assuming it has something to do with the CO2 in the beer.

I would say it's more of a supercooling effect than being due to the presence of the CO2.
