I've found most people who say that tend to be the ones who are having their actions interpreted as creepy, and that their major problem is they have zero ability to understand social nuances that define the difference.

Creep sees "Oh, the guy followed the girl up to the bar and asked if he could buy her a drink and she giggled and thought it was cute. But I followed this hot single mom home from her daughter's Kindergarten class and did the same thing, and she called me a creep. The difference must be appearance based double standards! Man women are just 'bitches'"

I mean yeah, there's guys that can hit creepy just by existing - if a guy has sallow skin, long unkempt hair that looks like it hasn't been washed in weeks, clothes that smell, and twitches a lot, he's creepy before he even opens his mouth, but I feel like this is called "extreme deviance from societal standards of grooming and personal appearance"
