This is another of those poses that, while fairly common in the world of glossy photos, one hardly ever encounters in everyday life:
. . . The longer I look at this type of pose (and it's hard not to, in this particular layout, what with the three brilliant examples), the more ridiculous it seems. Can you imagine seeing someone walking down the street like this? Or even someone just standing in line at the grocery store in this pose? Craaaa-zy!
