A person who is an obsessive
fan of the Toronto Maple Leafs
hockey team. They are die hards who would drag their genitals through 5
miles of rosebushes just to touch the sweat stains of Dion Phaneuf's jersey. Very cocky and overestimate the actual talent of the Leafs.
Billy: OH SHIT THE LEAFS JUST SCORED WOOOOOOH! GO LEAFS
GO! GO LEAFS GO! GO LEAFS GO! STANLEY CUP HERE WE COME!
Debbie:
Bro, it's still the first round of the playoffs. You're such a beleafer.
Billy:
