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"
