General English


  • noun an exhibition of self-aggrandisement, self-indulgence or other selfishness. The term dates from the late 1960s and derives from the notion that under the influence of LSD (on a trip) enlightened persons will lose their ego, while the unenlightened may experience a concentration of selfish impulses. Trip later took on the generalised idea of behaviour or idée fixe, and ego, simply egomaniacal or egotistic.
