Idiot Ball: Professional Wrestling aka: Pro Wrestling
After a rift with Arn Anderson, Ric Flair recruited Sting to be his partner in a tag match against Anderson and Brian Pillman at WCW Halloween Havoc 1995. Sting accepted. Then, as soon as he tagged Flair, he got himself an old-fashioned Horseman Beatdown.
It should be noted that Sting has fallen for this sort of ploy consistently throughout most of his nearly-30-year career. It seems, whenever this situation presents itself, Sting actively looks for the Idiot Ball.
Lex Luger carried it frequently in his WWF stint, but the worst instance of them all was when he had to fight off rumors of selling out to Ted DiBiase. The loudest voice of said rumors happened to be Tatanka. The two faced off at Summerslam 94 with the Native American coming out on top. After the match, Luger still couldn't figure out what the Million Dollar Man had to do with this.. until Tatanka beat him up post-match.
Any time a wrestler falls for a scheme or picks a fight or does anything wrong when simply watching the show would have fixed the situation. For example, Wrestler A shoves Wrestler B into B's good friend Wrestler C. C gets pissed and thinks B has betrayed him, when simply watching the video footage of A shoving B would prove it as all an accident.
