Canadian Cold Shoulder 

A type of killing as defined by earlier Dutch (militia) settlers in Canada.
"Canadian Cold Shoulder" is when you sever either the right or left subclavian artery with a blade in the shoulder as you walk past the victim. Do to the rapid loss of blood, the body will decrease in temperature especially around the area of the wound. If the victim survives they will most definitely feel ice cold, hence the name "Canadian Cold Shoulder"

Lamens terms: stab victims shoulder while passing by, victim will bleed out & only see your back as you walk away, "Canadian Cold Shoulder"

(theres debate whether or not Dutch settlers used it against the aboriginals or if in fact it was a swift defence mechanism used against the settlers)
