Eavesresponding
You're the type of person who reads a chat, doesn't understand anything, and still feels the need to drop in with a comment that makes no sense. It's like you're trying to be part of the group but you're just slowing everyone down.
'I'm not even here but I'm gonna say something.'
'You're all wrong and I know why.'
'I didn't even get invited but I'm gonna talk anyway.'
