Have you noticed that "Dude" has made a comeback? Good news for me, since I never really moved on from it. Although I'm pretty sure "stoked" is still mostly reserved for stoners.
But Dude! The reason I am stoked (stoner or not, it's effective) is because we bought a house today! We tried to put a contract on it Saturday but ran into a few problems, namely that somebody else beat us to it. We are lucky, and he backed out. It is going to be awesome.
