When you comment on a facebook status/post/photo and then loads of other people have conversations or comment complete irrelivent things which you can't be a part of because you either don't know the other people commenting or don't care ( probably the most likely )
Josh " I hate these Inbox Floods , i don't even know these fucking people !!! "
Josh " That poor girl commenting on your status , as the Dons of facebook we gave that bitch a inbox flood !! "
Adam " I know , it's because we care so much "
