A compounding factor is that (actual) Italian men are used to hard to get women, and their efforts are therefore scaled for such challenge. Never have I seen men try so fucking hard to chat up anything within sight than Italians.
I still vividly remember seeing a bunch of them moving through the nightclub crowd, chatting up women one after the other, failing, immediately moving on to the next one, etc.

(One could argue it’s the other way around : Italian women have developed a resilience up to the challenge of the insatiable appetites and relentless advances of Italian men)
