Why this word is great

FATUOUS — [Adjective] Obnoxiously stupid, vacantly silly, and complacently foolish. From Latin fatuus ("foolish, silly, simple"). Unlike "asinine," which implies a stubborn, obstinate stupidity, or "vacuous," which denotes a mere absence of thought, fatuous marries emptiness with a serene, self-satisfied confidence. It is the beaming smile of a spokesperson delivering a platitude as profound insight, the grandiose architecture of a plan built on wishful thinking, or the glossy advertisement equating a luxury car with spiritual fulfillment. It is the tranquil dignity of a mind untroubled by its own workings.

adj

Obnoxiously stupid; vacantly silly; content in one's foolishness.“A fatuous love affair can easily result in a fatuous marriage. A couple who hardly know each other and, indeed, may not even really like each other, make a commitment that has little chance of being honoured.”
