A meme "is an idea, behavior, or style that spreads from person to person within a culture—often with the aim of conveying a particular phenomenon, theme, or meaning represented by the meme"
The first usage was by Richard Dawkins in his 1976 bookThe Selfish Gene.
The meaning isn't a joke or an insult, not that you'd know, considering that you probably find Facebook a good place for unironic humor.
