What does "hova" mean, as in like, "H to the izzO, V to the izz-A" ("H.O.V.A.")?

Part 2: What's up with all the "-iz" stuff? Starbizucks (hehe, from the someone Kennedy Project), "I'm on the izEl with no place to gizo," or that new song I just heard, "dizouble dizutch."

What the hell?

Thizanks dizudes,
