Meme. You’d probably never even heard the term just a few short years ago. Once reserved for hardcore “All Your Base Are Belong To Us”-loving Inter-nerds, memes have since crossed over in a big way. Now examples of this “idea, behavior, style, or usage that spreads from person to person within a culture” (thanks, Merriam-Webster) have replicated like Mogwai in water, mutated via Photoshop and taken over the Web. In case you’ve been living in a hole, have a cheezburger and get up to speed by checking out some of the best/worst memes from the past year.
