This is a verb. To shizzle my nizzle means to take a salt shaker (aka shizzle) and have it expel its sodium-rich innards over someone's belly button. (aka navel, which leads to nizzle.) Shizzling someone's nizzle is a great sign of respect in many countries. Just don't do it in Italy. Ho boy... trust me.
He shook hands then shizzled my nizzle.
