Raa
This word originated in Rochester, England in the early summer of 2004. The word was used after "Ra" by Ebony dubsters (Drum n Bass tune) became popular here. The word Raa (pronounced normally with very little effort used in the aaaa part, said best if stoned) has since been used in the place of the word cool or to show that something is good or liked.
1: Dude, check out my bong!
2: Oh raaa!
