Cool things?

Cool things?
Some things that are cool/acceptable only in a certain context.
For example being captain of the chess club, cool on a college app or with those people, but almost anywhere else keep that to yourself unless you really like being made fun of.
Shaving your legs, cool for swimming, running, biking but other then that you just look like a woman and also need to use lotion all the time.
Singing, awesome in the shower or in the car or at a concert, but when your on the bus keep your mouth shut... Esp if you dont know the words or cant hold a pitch!Swinging out really wide for a turn. Needed when racing or turning really fast, but when you're scooting along at 5 mph its just lame (think si might agree with this one).
