Bitterness is a trait ingrained in the culture of professional wrestling. Ego and self-assurance are imperative in order for the so-called independent contractor to reach the top of his profession in a sea of colorful personalities looking to stand out.
The wrestler is a dedicated breed, especially on the national stage, as tireless travel and countless appearances turn a career into a way of life.
With the aforementioned ego and effort that is poured into making making one successful on such an elusive national stage come delusions of grandeur and, yes, eventual bitterness when it all inevitably dries up.
A book can be written on sour grapes in professional wrestling, but for now, we celebrate (and, let's face it, ridicule) those who have opted to harbor ill-will toward former employers who no longer require their services.
Ken Doane made a name for himself in the WWE as leader of heel faction the Spirit Squad who came up on the short end of the stick during a high-profile feud against Degeneration X.
As the odds-on-favorite to be the breakout star of a group of male cheerleaders who eventually flamed out, and whose talented former girlfriend reportedly upgraded for John Cena, Doane has a lot to be bitter about. And did I mention he was once booked as a male cheerleader?
Doane didn't have much to offer outside of a flying leg drop and was released from his WWE contract in 2008.
Doane has been very vocal during the ongoing suspension saga with Randy Orton, and has managed to squeeze in several shots at John Cena in his analysis.
Along with discussing past animosity between Cena and Orton, Doane also found time to explain Cena's indifference towards him, saying on Twitter:
"We were cool until last time I was there [Cena] hated me. Didn’t even want to talk or shake hands. Everyone else was cool though.”
But Doane wasn't done just yet. When asked if he was still engaged to Mickie James, the underachieving former male cheerleader quipped:
“Broke up with her once I found out she was cheating with John. #Rat.”
Doane has clearly found a source in which to channel his anger, and while he insists that he has come to terms with the fact that he'll never be brought back by the sports entertainment giant, the harsh reality seems to be eating away at him with every tweet.
Carlito was released from his WWE contract in 2010 after a second failed wellness test.
The talented Puerto Rican star had been tabbed as a potential top star, and was given numerous opportunities to ascend up the WWE roster before eventually getting lost in the shuffle.
Carlito rehashed his animosity towards his former employer during last week's episode of RAW that featured a hard-to-watch segment between Heath Slater, Roddy Piper and Cyndi Lauper.
"Im not saying heath slater sucks, hes just in a sh&%*y spot…hold up is that Primo and Epico on my TV? WTF?!"
"Heath is probably getting patted on the shoulder and told “Vince loved it” “keep up the good work, we got are eye on you” total bullsh%* lol"
While Carlito may be on to something with his player hating of Heath Slater, his sentiments are definitely born out of not-so-deep seated acrimony with how things ended in the WWE.
There is even a hint of jealousy in his tone as he took a shot at family members Primo and Epico after spending his final days in the WWE teaming with younger brother Primo.
Jim Cornette is a student of the game in pro wrestling and his sermons are almost impossible to tune out. However the habitual line stepper and expert bridge burner of a legendary manager hasn't exactly perfected the amicable split, nor will he ever.
Cornette has been fired or furiously quit multiple national wrestling gigs due to a high-strung personality, a quick tongue and a short-fuse.
Cornette balked on an opportunity for a put down, and entertaining as he always is, weaved within the fabric of a typical anti-corporate wrestling rant from Jim Cornette lies mean-spirited acerbity.
Konnan was a staple of the Lucha Libre undercard in WCW and later gained notoriety as a member of the New World Order.
These days, the majority of Konnan quotes are mean, angry and instigating.
Konnan publicly supported a familiar conspiracy theory that the WWE displays preferential treatment when it comes to their wellness policy, and went on to tell a controversial story about a supposed piece of advice that Shawn Michaels gave Rey Mysterio about doing jobs.
The former WCW and TNA stars' jaded commentary on the current pro wrestling scene came to a head during a heated personal exchange on Twitter with Chavo Guerrero Sr. where the two traded barbs in English, Spanish and childish.
Scott Steiner was bitter before being bitter was cool, and his salty personality was evident even when he was relevant.
Steiner doesn't like a lot of people, and that long list includes his most recent former co-workers Eric Bischoff and Hulk Hogan.
After parting ways with TNA recently, Steiner has spent the initial period of his newfound unemployment like any self-respecting wrestler, by ranting on Twitter.
In fact, Steiner's rants against Eric Bischoff and the Hogans among others were so vociferous, they lead to TNA filing a complaint against the former world champion for what they have deemed as "disparaging remarks."
Clearly at the point of no return in his mainstream wrestling career, Steiner's rage will only continue to be cultivated, as potent as it already is.
