(CNN) -- The former JetBlue Airways flight attendant who became an instant celebrity after he dramatically quit his job in August has a new gig and a new look.
Steven Slater dons a black hooded sweatshirt, adopts a mock menacing persona and walks with a swagger as he raps about the incident in an ad for a mobile communication app.
"Five hundred thousand miles in a little tin can/Maintaining forced smiles for the unpleasant man," Slater intones angrily in the video posted on YouTube.
"A steamer trunk squeezed into the overhead compartment/Were there room for that crap I'd make it my apartment."
Earlier this week, Toktumi -- the California company that developed the app -- tapped Slater as the official spokesman for its "Mile High Text Club" contest, which asks air travelers to submit their "craziest" flying stories.
Slater also will be one of the judges selecting the winner based on "originality and humor." The grand prize is a weekend holiday shopping trip for two to New York.
"We hired one of the most famous guys in the airline business today," said Peter Sisson, founder and CEO of Toktumi, in a statement.
"After talking with Steven, I realized that despite his dramatic approach -- which he regrets -- he was making a statement about the need to return civility and common courtesy to flying. He's a perfect judge for a contest concerning the current state of air travel."
Slater became a folk hero to many people after he cursed a passenger over a plane's public address system at the end of a flight, deployed the plane's emergency evacuation slide and used it to exit a flight dramatically at New York's John F. Kennedy International Airport in August.
Some passengers later said he also had been rude to them during the flight.
Last month, Slater told CNN's Larry King that "a perfect storm of bad manners" triggered his outburst.
Slater said his forehead got cut as he worked with a woman trying to wedge an oversize bag into an overhead bin.
After the plane landed, Slater said the passenger with the large bag began berating him. With the PA microphone already in hand, he said that he thanked the "respectful" passengers on board but not the woman who Slater said had called him a curse word.
Slater said he then grabbed a few beers from the beverage cart, looked outside, opened the emergency evacuation slide and slid down.
In October, he reached a deal with prosecutors and pleaded guilty to second-degree attempted criminal mischief, a felony, and fourth-degree attempted criminal mischief, a misdemeanor.
Under terms of the deal, he must enter a yearlong mental health program, which includes treatment for substance abuse, and take certain medications.
He also must pay a $10,000 fine to JetBlue for the cost of repairing or replacing the chute.
Slater has signed with a book agent to work with a co-writer on a story documenting his 20 years in the travel business. The book is tentatively titled "Cabin Pressure."
