Somewhere in the 1963/64 time frame a similar thing was going on at our playground.
Hyperventilate, crouch, and hold your breath.
Somehow, word got around that this could damage your heart and the fad went away.

Yep, we did that too as 12-year-olds somewhere around 1975. It wasn't too thrilling, though. We later moved on to getting drunk and spinning around a stick with your head down for 30 seconds, then trying to run in a straight line. Hilarity ensued, often followed by vomiting.

Never knew anyone who hung themselves, however. We may have been idiots, but we weren't fools.

"Hyperventilate, crouch, and hold your breath."

THAT's what it was. I was telling my wife about the choking high and the computer dust-off high, and said "I seem to recall doing something with hyperventaliting when I was a kid" but couldn't remember exactly. (Gee- I wonder why?!)
