Lets look at the statement FML or "Fuck My Life", just a bit deeper, shall we? One can take it at face value and assume it means that one's life is beyond reconciliation and should thus, simply be fucked, metaphorically, and be done with it.
Or one can look at it in a another way way. If we take the fucking to be literal, that is coitus with our existence, then that means one must physically engage in sexual union with our very being.
Now as we all know, there is good sex and bad sex. If it is bad sex, then all we gain from it is to be left feeling hot and sweaty and not much else, something no one finds very appealing. I'm sure this is what most would think the phrase means, if taken literally.
However there is another literal possibility. In this instance, instead of horrible sex, one has truly great sex. The kind of sex where afterward, your mind is left reeling in a storm of endorphins. Where the body and mind float upon utter ecstasy. Now if this is true, then not only would the physical you be left having one hell of an orgasm, but so would your existence. Since your existence is you, just the you over an extended period of time, one is left to assume that if one's existence achieves climax then you as a person must also do so but over the duration of said existence.
In other words, if done right, to "fuck my life" could very well mean to be left in a state of boundless writhing pleasure. If this is truly the case then I say we should all go about fucking our lives as often as humanly possible.
