I don’t know why, but if I figure in my head him telling that word with his voice and his Argentinian accent it sounds almost funny.
Since he is a foreigner, I assume he does not fully understand how vulgar and derogatory that term is in Italian. The result is “hilarious”, because as a native you realize he didn’t mean to use that word, like e.g. when a child uses a swear word thinking it is in the right context while it’s not.
