facebook cheater
A Facebook cheater is someone who's already in a relationship but still sends friend requests to another person just to flirt and mess around. They like every post, comment on everything, and chat nonstop like they're trying to get into the other person's pants.
Hey babe, I saw your post. You look amazing today. Want to hang out?
I just became friends with your ex. We have a lot in common.
Why are you always commenting on my photos? You're making me blush.
