afternoon ick

Sitting in a long committee meeting today, I couldn't help but notice the length of my (male) colleague's fingernails. There was visible white nail growth, easily up to 1/8" or more, past his finger tips, on all of his fingers. Ewwwww. Now, I find long fingernails kind of unclean and icky on almost anyone, but I guess I'm sexist enough to find it particularly disagreeable on men. (and no, I don't think he has a secret drag identity on the weekends.) Or is this some metrosexual thing I just don't know about? (not that I think he would understand the term metrosexual, either--he's definitely two or three generations older than that)
