possuming

Much more older than the above, going back at least to the '20s.

Possuming: The act of pretending to be unconscious, holding body, breathing and especially eyes still. Purpose normally is to hear what you normally wouldn't because the speakers think you're asleep.

"Sarah, quit possuming. We're going home." from Matryoschka Daughters
