I know extreme, and that's some extreme ping-pong-ing.

Of course, any sport you can play atop a launching rocket, or a soviet submarine is extreme by definition.

extreme: ex·treme /ɪkˈstrim/ [ik-streem] adjective, -trem·er, -trem·est;
1. of a character or kind farthest removed from the ordinary or average: extreme measures.
2. utmost or exceedingly great in degree: extreme joy.
