I feel like you can get away with calling your penis a tallywacker at this point.

Nose - penis

Penis - nose

Everything else remains unchanged.

mouth - soup cooler

beans and franks - jiggly bits

feet - go fasters

ears - sound catchers

Refer to both your nose and dick as your beak

I'm German and I've had a friend since primary school whose father used to call his nose his "Gesichtserker", which translates as "face oriel".

Call your penis a pecker or a schlong

Call your nose your beak obviously that ones great

Fingers/hands can be called paws, mits, grippers or grabbers, possibly claws or talons

You can call your knees and elbows "the ol hinges"

Obviously your feet should be called hooves or roots

Your belly can be called the incenerator or the disposall

Your hair is a mane

Your eyes are peepers

Pick two of any body part and start referring to them as "the girls".

Refer to your toes as your "little piggies"
