Not to put too fine a point on it, but maybe rather to put another perspective on this...
People are a lot of different things. Men will be men, boys will be boys, teens will be teens... yes. But even if you have all of the proper skills to avoid being a McDonalds cook forever (being a little facetious here), then you still have to hone the skill of knowing when to be a "teen" (wut ppl), and when to be "professional" (what people).
As a "man", I have to know when to not tell off color jokes- they might be ok on the golf course with the guys, but not say, in the store with my wife and kids. I might scratch and belch and pick my nose- but I sure try not to do it where it can "hurt" me.
It is not a matter of selling out because someone has power over you... it is a matter of getting what you
want. It is sales, it is politics... it is
using your intelligence to create the most positive situation for yourself.
Put another way, I think most adults would agree that being cool is way over-rated, and more often than not, trying to be cool usually causes some kind of problem for you. As you age (beyond high school), being cool becomes less cool than being responsible and wise.
So if you know how to spell, and want something from someone, and you properly assume that you are not in a room full of teens or peeps dat tink it is kewl to tawk to peeps that wiegh- learn to switch it off when it needs to be off...
Really- this is more "friendly advice" than me trying to be mean.
Now how do I segue back into fish???
