Facebook taggroup addict
A Facebook taggroup addict is someone who joins groups just because they're curious. They don't care if they have to join 2000 groups to get kicked out of Facebook. They just want to see what's inside, even if it's a stupid picture.
"I joined this group just to see the picture. It was a cat wearing a hat. I was not impressed."
"I joined 100 groups in one day. My phone was screaming at me."
"I joined a group called 'People Who Like Pizza' and now I have to live with that."
