sup-bro mentality

The mind state of a serious bro. You have got to be thinking about the swell, hanging out with top mints, longboarding, greeting others with "sup bro?", noticing your best bro's tan, and find yourself most attractive with your shirt off.

We were boarding down Hall when all of a sudden SC's sector9 split and he started freaking out. I told him to bring back the sup-bro mentality and things went back to being chill.
