A unit of culture transmitted from individual to individual, especially by some form of imitation. In common usage, the term refers to any individual piece of online content, usually an image paired with text, that circulates widely and spawns many imitations and variations. These cat memes are getting out of control.

From French, meaning "the more things change, the more they remain the same." In English, the phrase is used in reference to situations or problems that remain the same, even when people or things involved in them are different. We move into a fancy new office, and still, the server crashes all the time. Plus ça change, plus c'est la même chose. Plus ça change, eh? Even with the so-called champion of the working man in office, it's still the wealthy elite getting all the tax breaks.
