The stereotypical "man" in a homosexual relationship. The counter term is "mandissa," which refers to the stereotypical "female." For example, a mandingo would open the door for his mandissa, he would pay for dinner on dates, he would actively pursue his mandissa. Generally, the mandingo is the top, or the inserter, during intercourse. Most mandingos could pass for straight, while mandissas are obviously gay.
OMG! Look at that mandingo's hairy chest. I just want him to tear off my clothes and eat me.
