'live fast' means that you want to live live to its fullest because life doesnt wait around. wasting time isn't an option.
'die pretty' means you're always looking good. looks get you far in this shallow world, so if you've got it flaunt it. if your always pretty, you die pretty.
"her myspace headline is 'live fast die pretty'..."
"yeah, shes fucking hot(:"
Having an above average lifestyle; living well; synonymous with “living large”
That asshole thinks I’m just living pretty, but what he doesn’t understand is that I actually work for a living rather than being a leech, so OF COURSE I’m going to enjoy my money!
