Canada's history 

An act of taking a champagne bottle full of firecrackers deep into a opening in a willing or unwilling partner. The second phase of the act is taking a copy of "The Beaver" and smacking your partner in the face as you light the firecrackers through a hole drilled in the bottom of the bottle.

PS It is wise to keep the cap on.

I hear Sally had a little rectal burn after her Canada's History last night.
