This could very well be me. I do clap and yell, but I do not realize, unless tapped on the shoulder, that people are trying to get around me. I am very into the game. What I have observed is that usually when I clap it tends to get people around me looking towards the pitch. I will clap when we steal the ball or begin a good run and many of those plays will be missed if I was not watching intensely. Quiet with an intense look on my face, yeah, it does seem creepy. I'll buy one of those (Jason) goalie masks to make it lessen the creepy factor.
