A negros dreds hanging out from underneath the back of a fashionable "lid". The Nullet has become fashionable in football where the braided jeri curl flows clearly out and covers the brown skin. This can be attributed to the the negro associating himself with the days of the 'red neck's' mullet flowing out from under a truckers mesh hat.

When a negro uses the Nullet and wraps it up in a Nullet condom that is attributed to a red neck's Mullet Rat Tail.
Man that niggah has a mullet!, What cho talkin bout bro, dose be dreds. So what do we call dem dred's mullet. I guess that cookie got a 'NULLET'!
