Finally remembered the term I read last week, for the way guys, especially teenage boys, act to impress each other, often using girls as props, as Kavanaugh did to Ford to impress Judge:

Performative Masculinity.

Same thing he did on Thursday. Same thing Graham did. Same thing the clowns who today are bragging about bar fights.

Other species beat their chests, bare their teeth, or fan out their tail feathers.
