PMG stands for Poor Man's Gin, an alcoholic beverage perfected by a young aspiring Canadian. The official recipe calls for 3 parts vodka, 1 part 7up/Sprite/Mountain Dew, and a bunch of lemon. Top it off with some ice, and you are guaranteed to have a good night.

The PMG is much more deadly and powerful than an SMG. A Football Helmet should be worn when drinking a PMG, so you do not injure yourself throughout the night.

Pretty Mexican Girl. Abundantly available in the Southern California region. When drunk, they laugh like "ja ja ja" rather than "ha ha ha".

These girls usually maintain a certain level of integrity although a PMG may or may not be a sucia.
