Without the izzles it would sound like this
Can I jizz in your pussy/fanny.
Notice the izzle at the end makes it sound less crude.
"Can I jizzle In your Fanbizzle?"
"Man I was close to Jizzing in her Fanbizzle"
"Could of had kids If I Jizzled in her Fanbizzle."
"Man she makes me want to Jizzle in her Fanbizzle"
"Man she keep shaking that FanBizzle at me I'm gonna Jizzle"
"Jizzle FanBizzle that hoe"
