"meme" is an ancient term that predates the Internet. It was a well-established thing even back in high school English in '95 when we read and discussed Naked Lunch.
And it is in line with the earlier, non-internet definition of "an element of a culture or system of behavior passed from one individual to another by imitation or other nongenetic means." (There's another definition related to funny things being repeated, as opposed to behavior).
