The correct answer is: Slim Gaillard
“Immortalized by Jack Kerouac in On the Road (‘To Slim Gaillard the whole world was just one big oronnie!’), hip hits ‘Flat Foot Floogie’ and ‘Cement Mixer’, regular guest shots on Frank Sinatra’s CBS radio show, appearances in Hollywood movies (Hellzapoppin), disc dates with Bird and Diz, and inventing his own nonsensical backslang lingo (‘vout-o-roohie’) as published in his 25-cent Vout Dictionary and recorded under the title ‘Operal in Vout’ (1946) during a JATP gig, kept him high-profile when it mattered. Much to the chagrin of a number of scandal-fearing movie moguls, the debonair Gaillard also answered to the name ‘Dark Gable’ on account of the deep affection many top Hollywood actresses willingly imparted on this Cuban-born adventurer. It was such after-hours ‘entertainment’ that hampered Slim’s career for many years, prompting a successful re-location to Britain during the last years of his life.”
