Shaggy Rogers of Scooby Doo fame became somewhat of a dank meme god earlier this year. Reddit and Instagram were overflowing with memes depicting the slacker sleuth as a super-powered deity who is not to be messed with.

Memers have been using the format to make meta memes (Kyle/Drywall) as well as to make fun of people who are always ready for a fight. We've put together the cream of the crop but you can peep more over on the Know Your Meme page.
