Lendo estórias detetivescas ou vendo um filme com Bogart, Robinson ou Cagney e dando de cara com frases como estas:
"The sucker with the schnozzle poured a slug but before he could scram out two shamuses showed him the shiv and said they could send him over."
"You dumb mug, get your mitts off the marbles before I stuff that mud-pipe down your mush - and tell your moll to hand over the mazuma."
Purfa NO more, com a ajudazinha do Twists, Slugs and Roscoes:
