Facebook rollover
When people post the same comment on a Facebook post because they're blind and didn't see the other comments, which is literally the worst thing someone can do.
'This is the best post!', said by a person who didn't look at the comments and had no idea what was going on.
'I'm going to like this post!', said by someone who didn't even read the comments.
'This is my favorite post ever!', said by a guy who saw the first comment and thought it was a new post.
