While traveling outside of Canada, a Canadianmay introduce themselves by grabbing the other person's ass, balls or vag. Most commonly used by crazy drunk Canadian girls on vacation.
Hi, my name is Nicole (said while reaching around and grabbing the waiter Jose's ass with a firm Canadian Handshake).
Being the double-fisting lushes they are, a Canadian Handshake is when two Canucks greet eachother while both have a beer in each hand. In passing, they klink their cans of Labatt'sIce together and stumble on their merry way.
Terry and Ed bumped into eachother at the hockey party and gave eachother a Canadian Handshake. Terry likes men and Ed harms small forest animals.
