Eels - Most annoying supporters (IMO)who think they know the rules very well but actually have no idea, and ALL the referees hate them (which is true because they are tools)
Dragons - Think their side is the sh*t, until they lose then it must be the coaches fault, LOOK AT THE TEAM!
Broncos - I've found them to be laidback and not too worried about things.
Wests Tigers - Although lot of bandwagoners have jumped on, most have been loyal magpie or tiger fans for many years. Very big drinking (wests) and working class team.
Cowboys - Progressively become more prominant, generally good people who like to have a bit of fun.
Storm - Very few, but generally very nice
Sharks - FICKLE! (I'm a sharks fan too). Kimmorley plays well he is great, plays average who should never have been here. Look at Dykes in 2005, plays well he is the good ol' local boy, by the end of the season who is useless.
Manly - Either love the hate tag, or hate it.
Roosters - Mixture of nice people or assholes. Nice people have been fans since 60s 70s... Assholes 2002.
Panthers - Young Girls....
Warriors - To be honest i dont know nor have i met and warriors fans to comment.
Bulldogs - Very few nice fans, most from years ago, others arent fans are just dickheads.
Souths - Woodwork fans.. if they win they will appear.
Canberra - In their early to late 20s
Newcastle - Generally Arrogant
