directly translated this means "off the chain for shit" or something. of the chain is g-talk for something cool, and fo shizzle sort of means for real. So something that is off da chizzle fo shizzle is something that is REALLY cool.
"Fo shizzle my chizzle" is branched off the original "Fo shizzle my nizzle" which meaning "I concur with you whole heartedly my Africian american brother." "Chizzle" replaced "Nizzle" as this phrase is intended for asian people. This phrase means "I concur with your highly intellectual idea my asian brother."
