Sunset Life

A lifestyle characterized by partying, having a "free spirit" attitude, and/or otherwise living life based off how much fun you can have at any given moment.

The term was coined given the fact that if you live a life like this, you're likely always waking up when the sun starts to set.

Guy 1: Damn bro, did you just wake up? It's already 6pm
Guy 2: Yeah I was out partying all night.
Guy 1: That sunset life will kill you man.
