Coopsack's definitions
a backside that possesses qualities of a negro woman. the negro woman tends to have a big round bouncy booty that attracts many negro men with large penises. they tend to enjoy pouring baby oil on the buttoxes and slap them often before and during penetration. it is preferred by many over the negro woman's vagina because of the terrible folk tales of monsters dwelling deep in the vagina cavity.
