" Battle rappers having an insult contest. Men and boys compete in ritualized insult wars all around the world. Earlier we saw how the instinctive choreography of a standard human fight has been elaborated into the world’s various formal dueling systems. The same goes for the monkey dance of the banter fight, which always involves the same basic moves and rules. Two men take turns hurling boasts and insults. The contests draw spectators, who laugh and hoot as the men derogate each other’s masculinity, while also leveling hilariously vile attacks on relatives (especially mothers). All around the world, the verbal duel is a pure monkey dance for the mind, in which men compete in verbal artistry, wit, and the ability to take a rhetorical punch. Like other forms of the monkey dance, scholars have wondered why boys and men are drawn to verbal duels, and girls and women generally aren’t. This strikes me as a very male sort of question to ask. It’s sort of like a dung beetle wondering why humans don’t find feces delicious. Women avoid verbal duels not because they’ve been told it’s unladylike, but because trading the vilest attacks conceivable while vying in braggadocio just isn’t most women’s idea of a good time. Why don’t people eat feces? Because coprophagy isn’t in our nature. Why don’t women like to duel verbally? Because it’s not in theirs. "
