A meme (pron.: /ˈmiːm/; meem)[1] is "an idea, behavior or style that spreads from person to person within a culture."[2] A meme acts as a unit for carrying cultural ideas, symbols or practices, which can be transmitted from one mind to another through writing, speech, gestures, rituals or other imitable phenomena.

It doesn't just mean a stupid picture with block text over it that spreads on ******/4chan/facebook.

You're just too damn young to remember things without the internet.
