Back in the days when pro wrestling was switching from competitive to choreographed, "hooker" was used to describe wrestlers who had legitimate wrestling backgrounds (because they "hooked" their opponents in holds). The term is still used, although hookers have become relatively rare in wrestling these days, with the Godfather being retired, after all.
When Lou Thesz became NWA World Heavyweight Champion in the late 1940s, his status as a "hooker" was just as much a reason for him being given that position as his overall talent, especially considering that he subsequently wrestled in matches to unify the NWA title with other regional "world championships". The assumption was that Thesz would be able to legitimately win a match against an opponent who (for whatever reason) attempted to go against the planned finish.
Similarly, a cancelled storyline in wrestling used to be known as an "abortion." Of course, the sense of "terminated pregnancy" was around before the twentieth century, but was hardly ever used due to the practice being universally illegal and so offensive it was best not discussed.
More of a reference to anything in wrestling that did not go as planned to the extent of it being embarrassing or possibly exposing the business as a work.
CACTUS: "I'd like to talk about something else first. The Flintstones, Gene. I love The Flintstones. But you answer me this: [screaming] How many times does Fred have to buy the ribs before he realizes the car's gonna tip over? [laughing]"
MEAN GENE OKERLUND: "[laughing] I know that story! Give me a break!"
CACTUS JACK: "Well let's check back into reality. The fact is that Fred Flintstone's a cartoon character and Cactus Jack is just a mortal man. But not when it comes to the Nasty Boys! I'm not mortal anymore! I'm Cactus Jack! and this is Maxx Payne. Which means January 27, Clash of the Champions, on live national TV! We're going to take those gold belts from around your disgusting, fat, putrid waists and put 'em on our fat putrid waists! Gene, trust me, it'll be a do time, a dabba do time, we'll have a gay old time! BANG BANG!"note Maxx then made some non-Flintstones-related comments.
MEAN GENE OKERLUND: "All right gentlemen. Coming up in a week and a half on TBS, the 27th of January, these two men will meet the Nasty Boys on the Clash of the Champions."
CACTUS JACK: "[Interrupting] We'll have a gay old time! BANG BANG!"
The theme from The Flintstones started playing as the show went into a commercial break.
