A Quick Overview Of How To Say Col’cacchio
'Col'cacchio' is interesting. According to my source, it is an insult from the Roman dialect. (Italy has various regional dialects, some of which are so distinct they are considered different languages). 'Col' is Roman for the Italian 'con il' which means 'with the'. 'Cacchio' is, uh, a male appendage. It translates more along the lines of 'up yours' in English, and is considered rude, but not excessively so. It is also the name of a chain of an upmarket and extremely highly-rated pizzerias in South Africa. See this article for more information.
