I'm not sure about how the rules differ from H.S. to college,but one of my favorite college wrestlers (2time AA)and sure to make it his 3rd this year calls T.O in most if not all of his matches.He may be the most talented wrestler in D-II but his gas tank usually needs a little recharge mid-match. He's not the only one,this seems to be a common tactic in college wrestling.Just wave your finger in a circle and its drink time.I have never seen him do this to get out of trouble,probably because he is seldom in trouble.
