I thought I made it up...well guess not, but this is the definition my friends now use jigga for:
1) In Hindi, "jigger" actually means a close
friend,
homie, and so its a play on the "whats up ma nigga" saying.
2) A japanese
friend. doesnt have to be acting black or part black.
1) john:
yo Kumar, whats up
ma jigga? where's Harold?
kumar: Harold's probably watching the new movie, "Harold and Kumar go to Whitecastle"
2) kawasaki:
Yo Suzuki, whats up my jigga? where's Motorolla?
Suzuki: he's probably with Toyota watching "Suzuki and Kawasaki go to Whitecastle on a Motorcycle"
