A Sprang-Capelle is a fake ass gangster who thinks he's a true Capone, but instead is a Sprang-Capelle loser who cannot even get the surname right. They are usually total faggots and pedophiles and crazy because of all the drug-filled orgies they participate in. Typically of Italian or white descent, they are reliving the glory days of the mob that they never participated in.
