facebook potato
A person who spends more time on Facebook than they do in real life. They’re like a ghost who only shows up for likes.
I saw my friend at the store and I didn't recognize them because they were wearing a shirt and not a Facebook profile picture.
I asked them how they were and they said 'I'm fine, just scrolling through my ex's photos.'
They went to a concert and took 100 pictures but didn't talk to anyone.
