Wear black knee highs with shorts.
Not comb hair. It is called the "mussed" look. thank you Robert Pattinson.
Go vintage by pulling out there favorite shirt from college. We have to go shopping at "vintage" stores and spend lots of $$ to get the same look.
Can wear socks with sandals.
Adjust themselves in public and we have to ignore it.
Pick their nose
Have hair sprouting out of odd places
Wear t-shirts that have their belly sticking out of the bottom
Eat deep fried meat five meals a day
Discussing the size, color, and nature of their poop
If they don't like their hair they can just shave their heads.
* fart in public and think it is funny
*carry on a whole conversation with just the word "Dude"
* Pee standing up
* Go without shaving for that rugged look.
