A smart way of saying "
Life is a bitch!". Someone who has oppressed anger and fed up with life, yet at the onset wants to look normal, would use a phrase like that. Gives the connotation that the user of the phrase is very
happy-go-lucky, but on closer
examination one realizes that the user is going through a hard time.
Heard it in one of the sayings "Sex, booze,
rock and roll; Weed, speed and birth control;
Life's a beach and then you die;
so fuck the world and let's get high"
