I have actually been catcalled before, but it was in somewhat close proximity. It was in Vegas and it was a group of girls who were walking toward me and one yelled, "Hey! She likes your hair!" (I have anime-esque hair)

I was more confused than anything, then embarrassed, then amused. Us guys get so little attention that I've been going out of my way to compliment other guys in a non-flurting way.
