Facebook taggroup addict
A Facebook taggroup addict is someone who joins every tag group like it's a holy mission. They don't care if the group is about cat memes or deep-fried pizza. They just want to be part of everything, even if it means getting kicked out of Facebook.
"I joined this group called 'People Who Hate Mondays' just because it had a funny picture of a sad donut."
"I became a member of 178 groups in one day. My friends think I'm crazy."
"I joined a group called 'People Who Think They're Cool' and now I have to live with that."
