CH is an abbreviation for "Club de Hockey Canadien", an NHL team. The Montréal Canadiens are the oldest established National Hockey League franchise. They have won 24 Stanley Cups, eleven more than the team with the next largest number.
Dude: Le CH a encore perdu? (The CH lost again?)
Dude 2: Ouais, ca sens pas la coupe s't'année (Yup, it doesn't smell the cup this year)
