"Journey" that a narcissist goes on

EGOTRIP

Think of a self-centered adventure where the destination is all about "me, myself, and I"—often taken metaphorically rather than literally.

The clue plays on the idea of a "journey," which usually means a trip, but pairs it with "narcissist" to hint at someone obsessed with themselves. "Ego trip" is a common phrase for self-centered behavior, and removing the space gives the answer "EGOTRIP." It’s a clever blend of literal travel and figurative self-importance.
