Defeated male lurks.

When all the lionesses are in heat and all want to be bred RIGHT NOW and multiple times (and will bite the scrotum of the solitary male to… stimulate him into action), then it’s the hour for all the defeated males to shine.

Seriously, this is a relevant part of lion pride sociopolitics. It may also figure into why the dominant male tends to kill the cubs of the lionesses when there’s doubt as to their heritage.

When I researched alleged murder gangs of lion males there’s not much evidence for them, but discovered insatiably horny lionesses (seriously) is the way defeated males get their day.
