Would you be flattered, annoyed, or creep out if someone says "you are mine"?

Complete strangers. Yes. Psycho...

I'd be seriously creeped out.

Only one person in my life used to say so.
And she was not a stranger but the closest to me.

BTW, your username is beautiful.

It really depends on if I find them attractive and how well I know them.
Regardless though, alarm bells would go off if they were total strangers.
If it's from someone I know that I like, then that would be exciting 🥰

Id say like hell i am .and walk away

Now u need to put a pic up or i consider this a troll account and BLOCK.
