My wife is from the southern Salento where, as the wikipage itself shows, a different term is used. As it is common in Italy often dialects radically change withing a dozen kilometers.

Anyway, I do have good friends from Taranto, and this never came up; then again, there are so many synonyms of 'penis' in Italian and its dialects that if we were to avoid all of them we would have to rip out half of the dictionary.
