In the recent past, I spent a good number of years working as a coder on Sketch. Before that, various games and interactive music thingies.
It came originally from the Underworld song “Born Slippy”, which I really liked back in about 1995 when I was working at the Multimedia Corporation.
I mutated it into “born sleepy” and started using it as one of my email signatures, and it kind of stuck.
It does describe me quite well…
