The game system that a small child is *actually* playing, as opposed to one that they *think* they are playing, when you give them a controller that is not connected to anything.
Player 1: Jane, come over and we can gank some scrubs on Call of Duty!
Player 2: I don't think so Wendy, your kid gets upset when she doesn't get to play.
Player 1: Don't worry about that, she's like, 4. I can just let her hold a spare controller and she can play the pretendo!
A cheap rip-off "Nintendo" console/device that plays Nintendo or Nintendo-esque 8-bit games. Usually comes in extremely cheap packaging, is never found in retail stores, and runs on AA batteries with A/V outputs on the device.
dude 1: Dude, go play your Pretendo and shut up.
dude 2: I'll kick your ass at a game of Pac-Man...
dude 1: Mario Brothers.
dude 2: You're on.
dude 1: Well, as soon as you find it in this list of 76,000 duplicate games...
