A display of dominance females of ANY species act out to prove their intellectual and spiritual superiority over their male counterparts.
(Spoken in a David Attenborough voice) "On occasion, the lioness will sneak up and pin the slumbering male on the ground where she will then begin humping him from behind, demonstrating that, although the male may be king, she is REALLY the one in charge. This display of dominance is called yumpin'!"
