Nice one. I was a bit lost as wasp-waisted used to be a description for the curvy actresses of the 40's and '50's, not some dude.
Yeah but that was in reference to their proportions wasn't it? Hips, boobs, graduating down or up to a tiny waist, classic hourglass figure. I have seen the term in bodybuilding for a while too, obviously the former has better mental associations.
