Wishing Troll Syndrome
The condition most noticeable towards the end of swim season in which ones hair becomes excessively dry, crappy, dead, and occasionally green, and can be made to stand straight up like a wishing troll. The only know cures are shaving and a buttload of conditioner, and can help be prevented by using a swim cap and tons of anti-chlorine shampoo and conditioner.
Dude what did you do to your hair?" "I didn't use a swim cap or take care of my hair all swim season, and now i have wishing troll syndrome.
