FABUSE - A weak version of 'Frape' where you chat up someone on anoth

A weak version of 'Frape' where you chat up someone on another person's Facebook post like you're not a creepy ghost haunting their social life.

Hey, I saw your friend's post and thought I'd say hi... just for fun. :)

I commented on your friend's photo like I was invited to the party.

I messaged your friend's crush on their status update because I'm a sad, lonely mess.
