    I took biology in 1996; it wasn't a thing yet. Someone else claimed it was already widespread by 2001. I don't think I encountered it in the wild before 2005, but it could have been much later than that.

    KnowYourMeme suggests the phrase originated in a textbook from 1957, but it didn't reach memehood until 2014.
