"Eat Me Raw,
Don't stop there,
Get a little hair!"
Modern use is usually derogatory, see example
(syn.- see "balls deep, balls and all")

3. - "She wanted it harder, so I gave it to her balls 'n all- she screamed like she was dying, came so hard she threw her back out, then told me she loved me."
example 2: I'll have a supersize combo, balls 'n all!
