The current generation has gone through the fads of planking (previously 1 and 2), cone-ing (previously), owling, leisure diving (both previously), and even Tebowing (previously). Posing-for-pictures fads are not a new thing, though. In 1959, near the end of the relatively well-known phone booth stuffing craze, there was hunkering.
First we started with planking, then owling, and then it go so hot we just dove in. We're all familiar with planking. (Some tragically so.) An obvious exponent would be owling (even by celebrities! and more celebrities!) Now we're leisure diving.
