What is -izz-?
1.
The midfix -izz- is used as an embellishment to add syllables to words, perhaps for purposes of meter. When context allows, sometimes the remainder of the word is actually omitted.
Regular: "I'm going out to walk the dog."
Instead: "I'm going out to wizzalk the dizzog!"
Or: "I'm going out to wizz the dizz!"
2.
Clarification: the -izz- is placed after the initial consonant, or if the word begins with a vowel, at the beginning of the word.
"Ow, I banged my arm!"
"Ow, I bizzanged my izzaarm!"
"Ow, I bizzed my izz"
3.
It is simply ebonic pig latin.
Pig Latin becomes Pizzig Lizzatin.
Fo' Sho' becomes fizzo shizzo, or fo shizzo, which then became shizzle, in and of itself a new slang word.
