a small round nut dipped several times in butter. Eaten by the most obese of wisconsin society (Mrs. Hose).
Butternut(s) can be used in many diffrent recipes for instance the butternut candy bar...1 stick of butter with large butter nuts protruding from every inch of its surface.
She dipped her husbands small genitals in BUTTERNUT sauce before she licked them clean.
You little shit, give me my god damn butter nuts before i fucken cream my jeans and fucken eat your ass out.
Mrs. Hose shrilled in pleasure as she rammed her face full of the delectable butter nut.
And one final example!
Mrs Hose bathed in the butter nut as she squirted butternut shampoo over every inch of her 500lb body.
