A type of person who loves to share Hentai with others, despite nobody likes it or wants it to be shared with them.
He can also be an extremely annoying asshole if you don't add him into your Hangouts group in fear of him spamming Hentai.
If he is not allowed to join you in a game, he will find your server and will grief until you quit the game out of frustration.
He has many friends who are just like him and will gang up on you to do his bidding.
If you see a Johannes make sure you trust him before you invite him to your Hangouts.
