When you are quiet for months but decide to come out of the woodwork to pile misery onto people's night with the snide headline "Hey Ohio St Fans lets hear excuses", you might be a troll.
When your go-to response to someone's post is a tissue box or crying Lebron James, you might be a troll.
When you are butthurt and can't get over the need to shovel crap, when you follow someone so you can heap your own brand of garbage on their life, you might be a troll.
If it looks like a troll, if it sounds like a troll, it's probably PYT.
