Um, I must have been leading a sheltered life all these years, cuz I've NEVER heard this term before. Of course, I can easily (and happily) imagine what this may be referring to LOL. In fact, I remember saving a catalog from decades ago of a young man in a bathing suit showing off, well, you know... In any case, it was homoerotic enough for the likes of me, even though the firm was not at all so inclined, and has since even cleaned up that one m2m oriented "faux pas" of yesterday in favor of heteronormative adverts, much to my chagrin.
This continues to be a great story!
