How do you deal with being sexual harassed in public by a passing stranger?

I’m talking about some dude – or a group of them – calling out to you that they “hate to see you leave, but love to watch you go.” I was just riding my bike wearing my typical bike pants that are not revealing, but definitely made of spandex material.

It just made me sick, and I wasn’t expecting it at all. I didn’t even think they were talking to me until I looked back and they made some pretty awful sexual gestures. :(

How have you realistically responded to situations like this? Do you just ignore them and try to repair your own ego?
