Just cheer and boo. Thats what I did on my first show. Start chants is good too. I start the Wooooooooooo chant for Flair at a Raw show in 2004 and everyone joined in and the show didn't start yet. Great times they were.
To be honest ive been to loads of shows and most people just sit in their seat and watch it like they do when they watch it on TV. Its not really anything hard to do
I HATE Those people! whats the point in going!?
I mean seriously..
just go and be an ass hole to the bad guys, and cheer on the good guys. You'll have a ton of fun. Dont read too much into things though.. if a wrestler botches a move, forget about it there and then. Dont start a "you ed up" chant or even join in one.. thats the kinda crap that ruins shows in my opinion. Just let go and have fun. The people sitting all around you are there for the same reason so talk to them. Its great fun.. no one cares who anyone is or what anyone looks like or where anyone lives or what anyones job is.. people are there to see some wrestling action... just go along scream til your throat is hoarse..
