I grew up a hockey fan all my life since I could skate at age 2, and by far the most annoying sports fan I have ever encountered are the Montreal Canadians fans. They come by the bus loads to Boston, a few years ago they booed the American National anthem up in Montreal and the next game back in Boston we stood up and applauded the singing of the Canadian national anthem. They also do that very annoying soccer/football cheer that "Oh Lay Oh Lay Oh Lay" chant. So FO's folks which team has the most annoying fans.
