patteran or tacit knowledge

Ranker--and it is amazing what boutique web-sites one can find--showcases the top 50 internet memes of 2011, via Neatorama, which is curating many of the superlatives, achievements and things better forgotten of the past year. Some of these are really funny and flooring and even though for the best ones only a glimpse and no explanation suffices to communicate everything without killing the joke, I do like the Cliff's Notes and appreciate the background with plenty of inspirations and variations on a theme. What other statement in short-hand, writ small, might you include here?
