Facebook rollover
When someone adds their two cents to a Facebook post even though they didn't read the comments and it's just a waste of time and energy.
'I agree!', said by a person who hadn't read the 10 comments above them.
'This is the dumbest thing I've ever seen!', said by someone who didn't even read the post.
'I'm going to die from this!', said by a person who didn't even know the post was about a cat.
