The big timers are the ones that generally cut themselves with razor blades, although sometimes, some of the guys, especially on the lower circuits get REALLY messed up doing stupid stunts.
More or less, Pro-Fake Wrestling is a soap opera for 14-35 yr old males....
If you look at it as a tumbling act and not a sport some of it is fairly good. However these days its mostly arguing and posturing before the camera.
Yeah, it's dangerous to cut yourself though. Eddie Guerrero did it in a match and ended up nearly passing out in the ring because of the blood loss, ended up in the hospital
