- Did the hot date you were kind of into try to touch your boob without asking you? Creepy! (acceptable)
- Did the ugly guy two tables over compliment you on your looks when you were both trying to get a drink at the bar? Creepy! (not so acceptable.)
- Did the guy you were dating for a few months ask you for a 5' in-person conversation after you decided to break up out of the blue over SMS? Creepy! (that one happened to me and I felt personally threatened by this woman's implicit threat of slander)
It's also interesting how prevalent the notion of "creepyness" is in the US. Whereas in other cultures the same guy would be considered annoying, inconvenient, misguided or justifiedly threatening, here a blanket term is applied and everyone accepts it. The same principle applies to a lot of emotional stuff, where Americans apply very coarse "pattern matching" to behaviors that other cultures are way more nuanced about.
Though it is not at all appropriate to share such information on a public online forum.
