8 years as a wrestler. 2 and counting as a ref. I've given a few guys their last match, even more their first match. Bad matches and good matches, big crowds and 3 drunks, some on TV, most not.
At almost every show there has been a couple of guys who are trying to break into the business. Trainees they are usually called, friends of some other work who want to try their hand. Some actually make it to their first match, most of them have no clue how to act. So hear it is, part 1 of the rules to living the life and not getting the crap stomped out of you in the ring:
1) Look like you belong there. You don't have to be ripped or huge or look like a movie star, but you need to look like you belong. Get some ring gear, stuff you only wear in the ring and keep it in good repair. No holes, and clean it regularly (or at least use febreeze).
The imitable Dusty Wolf once said, and I paraphrase, no one is paying to watch two guys who look like they just walked in off the street roll around for ten minutes. And it's true. Even the guys who successfully pull off gimmicks like being a biker or a thug or whatever have some gear, boots, pads, whatever.
Gear is pretty cheap too. You can find a simple singlet for $25 on the internet, a set of mat shoes and kickpads will set you back another $50 or so. So for $75-100 you look like a pro.
Take care of it. That's your livelihood right there. Treat it like that. Treat it good and it will last. Sew up tears, clean it. And get Febreeze. Before and after you wear it, spray your gear down. If I step into the ring and I get a face full of rancid smelling tights, I'm going to make sure your neck feels it the next morning.
