freestyle

1) Refers to music (usually rap and sometimes techno) where everything is made up as they go along. In rap, people make up lyrics as they go along, but in techno, the DJ improvises beats and mixes songs on the spot.
2) A move in sports (especially extreme sports) where someone pulls off a stunt that doesnt really follow any guidelines for any regular move.

1)That freestyle music is wicked.
2) I'd like to see more of those freestyle moves
