Then you're using a different definition of "piropos" then pretty much everyone else in Argentina. The Mayor of Buenos Aires in 2014, discussing street harassment: "A todas las mujeres les gustan los piropos, aunque les digan que lindo culo tenes" (All women like compliments, even if you tell them 'what a nice a** you have'). So, according to the Mayor of Buenos Aires, a catcall is a piropo. According to you, it's not. There is definitely a link between piropos and street violence. Of the 100% of Buenos Aires women who had been the victim of piropos, 59% experienced vulgar language or gestures, 47% were followed, 37% were exposed to the catcaller's genitalia.
