As above used to exclaim astonishment or exclamation, but been used in Sarf' London for many a year now.

Often pronounce one of two ways - Ra and Raaah. Raah being the full exclamation, hanging on the "aah" for as long as possible. Ra being the shortened snappy version for less astonished moments or when less heavily stoned and wanting to shock your friend with a sudden loud noise
