The deeply worrying thing about catcalling is that the catcaller must know that their target isn’t going to turn around and fall in to their arms pleading ‘oh dear my please have sex with me here and now’. A lot of the time they know that. Often they don’t do it for that, someone who shouts ‘nice tits’ from a van isn’t trying to date you. They’re trying to humiliate you, reinforce their dominance over you; it’s an exercise of male power. It’s a way of communicating ‘I can say and do whatever I want to you, no matter how inappropriate or how uncomfortable it makes you feel, and you can’t do anything about it.’ Catcalling is not a compliment, it’s a threat.
