Capicola – made from dry-cured whole pork shoulder or neck. The Italian word, “capocollo'” is of Tuscan origin.
Gabagool – This is an addition to the previous definition, which is half right. “Gabagool” is slang for “capicola.” It is not a mispronunciation, but is instead in Napolitan dialect, which is what the Sopranos and many Italian-Americans use.
The rule in this dialect is to chop off ending vowels and to voice unvoiced consonants.
