Plural of braggadocio; multiple instances of vainglorious boasting, or multiple people who engage in empty boasting and self-promotion.
Simply the plural of 'braggadocio' (from possibly Italian 'bravaccio'). This form acknowledges that bragging can be both a repeated behavior and a trait found in multiple people.
In a room full of braggadocios, there's actually an interesting social dynamic—since everyone's claiming superiority, nobody believes anyone, so the boasting becomes almost comical or self-defeating!
