The practice, habit, or quality of indulging in excessive boasting and vainglorious self-promotion; chronic braggadocio.
From 'braggadocio' + '-ism' (indicating a system, practice, or ideology). This word elevates bragging from an occasional behavior to a systematic character trait or cultural pattern.
Braggadocianism as an '-ism' suggests it's almost a philosophy or lifestyle—which is actually a clever linguistic way of mocking people who make boasting their entire identity!
