Ass Slap on Stage while Wearing a Thong to Compete

A competitor is wearing a thong on stage. His competitor beside him can't take his eyes off his glutes the ENTIRE show. He finally gives in to temptation and gives him a nice slap on the ass in front of everyone. Then he gives a fist bump to downplay what he did. The competitor in the thong is quite the exhibitionist and is absolutely loving the attention. I wonder what happened backstage before and after the show?
