John Koble, Capone's best biographer, noted that nearly all the gansters' nicknames were applied by journalists who wrote about them--not by themselves. As Kobler pointed out, they didn't greet themselves with, "Yo, Greasy Thumb," or "WasssUPPP, Three-Finger!" In fact, most gangsters hated those nicknames (Bugsy Siegel being the prime example--call him "Bugsy" and you'd be on the floor!). Same with Capone and "Scarface": the only nickname he favored was "Snorky."
