Facebuddy - A person you have on your friend list but they're not your f

A person you have on your friend list but they're not your friend. They're just a background character in your Facebook story.

My facebuddy is my gym teacher. He doesn't know I'm his student. He's like, 'Hey, you're my friend? I don't even remember you.'

I added my facebuddy because he was my classmate in 2005. Now he's my best friend. What even is time?

My facebuddy is my cat. He has 2 friends. I have 100. He doesn't care.
