Well, there was the "Meat Puppets", formed in 1980.
And then Terry Bisson's "They're Made Out of Meat", published in 1990:[0]

So yeah, it's a term that we old geeks use.
Recent usage by John Markoff:
> "True Names" by Vernor Vinge (1981): "The basic premise of that was, you had to basically hide your true name at all costs. It was an insight into the world we’re living in today … We have to figure it out. I think we have to go to pseudonymity or something. You’re gonna participate in this networked existence, you have to be connected to meatspace in some way."
And yes, we "have to go to pseudonymity or something". If we care about privacy, anyway.
