What does Brownstuff mean?

Brownstuff meaning in Urban Dictionary

A name directed at a woman that is a good buddy and whom loves to celebration and may dancing AMAZINGLY. Nearly the same as Redstuff but much better at performing every little thing than this lady. Unfortunitly, Brownstuffs really do not prefer to work that much but make up for it in the way they shout support to big crowds of older people on longboards. Possibly the best friend a lady might have!
