baseball cap 

Device which, when fitted to the head of anyone driving a car, immediately removes any concern they may have previously exhibited for their own, their passengers, and, well, anyone elses safety.

Especially effective when driving 'modded cars'. See kev.

Tracy thinks that Trevor's baseball cap makes him a much better driver.

Canadian base system 

The Canadian base system is:

- first base: kissing and fondling breasts

- second base: hand job, fingering or oral sex

- third base: sex, and

- home base (or fourth base): sex with a hockey puck used as a dildo and maple syrup used as lubricant.

Katie: All my friends from back home in Northern Ontario go to home base (Canadian base system) by the time they're 15.

David: Is this why hockey and maple syrup are so popular in Canada?

77th base 

Doing every single Alaskan _____ in one session. These include but are not limited to the Alaskan earthquake, Alaskan chopsticks, Alaskan crabhammer, Alaskan Gold Rush, and the Alaskan Umbrella. An Alaskan Snow Dragon must be the last sexual act performed. Good luck.

Guy 1: Dude I got to 77th base with sarah last night.

Guy 2: Get away from me you sick mother fucker.
