It’s annoying if you get drunk and start trying to get me to kiss you and being very persistent on that or maybe if you’re not drunk but you keep finding reasons to give me long drawn out hugs in the pretense of friendliness. Or alternatively if you don’t know me and just see me somewhere like the bus and keep trying to get my number. Creepy to me is intimidating, like if I reject you and you find out where I work and you keep showing up to my workplace by the time I leave trying to “hang out” and I need to find some people to leave with me so I’m not alone with you. If you know me and you want to demonstrate interest it’s fine.

I will say something a little controversial here and suggest for your own sake that you don’t look for relationship advice on this site.
