After two Florida teens shared a video of themselves torturing and killing an endangered gopher tortoise online, 4chan members rallied together to identify the perpetrators and bring them to justice.

During Holland's World Cup match against Brazil this weekend, Dutch soccer player Jasper Cillessen was photographed squatting against the goalpost halfway through the game, inspiring Twitter users to launch a photoshop meme with the hashtag "#cillessensitsonthings."

The actor left himself wide open to become a meme when he posted a picture on Instagram of himself enthusiastically embracing a tree, and he's embraced the parade of photoshopping that followed.

The latest sketch comedy webisode from CollegeHumor introduces "Columbusing," a neologism for when white people "discover" something that has already existed before.

Nearly four years after the last great war between 4chan and Tumblr, the two heavyweights of the memesphere are once again butting heads over their opposing political stances.
