During a rugby match once, I constantly made fun of a player on the opposing team for wearing leggings. I did it the whole match, it was great I came up with some real winners as far as insults go. I was then informed by a friend of mine who is a physical therapist that sometimes people wear leggings (mind you it wasn't cold out) because they had to have their lymph nodes removed and they need the leggings for circulation. I then felt really bad.
