A list that is unfortunately necessary
  1. 1.
    If you are a woman, expect that it will happen.
    This pains me to say, but if you know that it's a possibility, you are already on the offense.
  2. 2.
    Ignore said catcaller.
    No matter how close in proximity they are, the vulgarity level of whatever they said, or how abruptly/loudly they may have shouted, try your best to remain completely unresponsive. They exist solely to receive your attention (whether it's positive or negative).
  3. 3.
    Continue walking/going about your business as if it hasn't phased you.
    (See #2 and do NOT take the offensive comment personally. More on that later).
  4. 4.
    While this is happening, however, try to get/keep the catcaller in your peripheral vision, without turning your head to indicate you are doing so.
    On the rare (but not *that* rare occasion they decide to follow/physically approach you, you won't be caught off guard.
  5. 5.
    Perhaps an obvious point would be to not make eye contact, either.
    Bonus points if you happen to be wearing sunglasses, as these hide not only the direction of your vision, but also any facial expressions of anger, annoyance, fear, or sadness you may showing. These are all valid emotional responses to have, but don't give them the satisfaction of even a slight response.
  6. 6.
    Resist the urge to flip them the bird, curse at them, or otherwise retaliate.
    I know that you wanna "stick it to the man" for women everywhere, and I totally feel you. But your safety is more important. These people have fragile glass egos and cannot handle being confronted.
  7. 7.
    And most importantly, DO NOT begin thinking, even for a second, that you were catcalled because of what you were wearing, the way you were walking, etc etc etc.
    This is exactly what they want you to believe, but the issue is with them, not you. You have every right to dress/act/exist how you want.
  8. 8.
    Continue being a badass in all aspects of your NYC existence. Repeat steps 1-7 as needed (which hopefully is not often).
