get it all the time down here in Fort Lauderdale. when people say "hey...Bills fan!" - you dont know how to react. initally you think, "hey this must be a fellow fan that wants to chat", but most of the time its followed by "BUFFALO SUCKS!"
funny thing is i notice this when i approach/notice other bills fans, when i say "hey , you a bills fan?" they always seem to hold back a bit in fear that my next words would be BUFFALO SUCKS.
