Nov 27 Word of the Day
A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.
That fucking smooth brain put his shirt on backwards again...

That smooth brain is dumber than a pile of shit.

Only the absolute most gangsta sport in the entire world. Duh.
Basicly, climbing to the top of big rocks. Really big rocks are called highballs. And you don't climb a boulder; you "send" it.
The great thing about it is that all you need is a chalkbag(Prefarably filled), climbing shoes and a crash pad. If you're thrifty all under $200 bucks--and they last forever.
Dude, this weekend I'm going bouldering on that highball that you couldn't send.
