Twerking is the mating display of the female Africanus Americanus. When the female of the species goes into estrus, which is nearly continuous except for 1 week out of a lunar month, she "twerks" to signal her availability to males in the area and to display her sexual fitness.
In the display, the female arches her back and raises her buttocks into the air and gyrates the pelvis using quick, jerking motions, causing the tissue in the buttocks to jiggle and
bounce in such a way that it moves separately from the pelvis itself.
The
male of the species, upon seeing such a display, is compelled to approach the female, offering his genital region for the female to
grind and jerk her buttocks against.
The display culminates when the female and a
male go to a less public area to
mate, such as a bathroom stall or the backseat of the
male's 1989 Chevy Impala. The encounter is often brief, the male losing interest almost immediately after ejaculation. But the female, if her level of excitement is
high, will often invite other nearby males join in and
mate with her.
Her ability to handle males can be quite
high. In the wild, females have been observed mating with groups of 20 males at the same
time.
If successful, the female will give birth in 9 months, raising the child as a single parent in habitats known colloquially as "the
projects". The child will stay with the female until he or she reaches adolescence, at which point it will begin to produce offspring of his or her own.
