A word created and used only by the embarassingly inferior of people, mainly heavy-set blonde chicks who'd like to think they're highly creative and original for using the word. Used appropriately, "wonderfuck" would referrence the
mental state of any given
individual who's recently
experienced any heavy, typically negative, intrinsic or extrinsic experience. Despite rolling off the tongue nicely, you do not want to be caught dead in public saying this word. You'd just as well fart as noisily as possible and slap everyone in a ten-foot radius, as it'd have the same effect on people.
Girl: "Whoa, man. My cat just died, I was evicted from my
apartment and
the doctor told me earlier that I have tumors in my
ovaries. What a wonderfuck."
Man: "Yeah, well you deserve it you damn cunt."
