Face-Friend
A fake friend who you chat with online like they're your bestie, but when you pass them in real life, they act like they don't know you. You talk for hours about your feelings, but they wouldn't even say hi if you paid them.
Hey, I just saw you at the store. You didn't even notice me.
We had a whole convo about my ex, but you didn't even wave.
You posted about my life, but you wouldn't say hi.
