I hear the government introduced a GST, so I'll have to pay an extra 10% for the keg I'm buying for tonight's GST party.

GST

The tax (along with stuff like the the 1980s recession, and that Chretien ad) that lead the downfall of the Progressive Conservative Party in 1993. It's still with us Canadians since it was introduced, but thank God that Stephen Harper and the new Conservatives lowered that tax by 1% and that they're going to lower that again by 1% at the beggining of 2008 (the Liberals promised that they would destroy the GST ath the '90s, but they never did it anyways).

Gahhh! GST pisses me off....
