Is it "For fuck sake" or "For fuck's sake"?

It's for a work e-mail, so it's got to sound professional.

@dgar I assume the sake is owned by fuck, therefore, "for fuck's sake". Or if the sake is owned by another object, "for fuck sake". It's usually the first, but the seccond is possible.
@dgar For fuck's sake. Or, put another way, for the sake of fuck.
@dgar You definitely don't want to up-fuck this.

@dgar The Cambridge Dictionary indicates that it is "For Fuck's Sake".

@CisopSixpence @dgar Finally someone brought the big guns. Also, it's kind of obvious that it is "fuck's" because if it's not a variant of "For God's sake" (which is well established), I don't know what is.
@dgar I'd go for the apostrophe. It is, indeed, of the utmost importance to use correct spelling when engaging in profanity.

@dgar It's English, so there are two answers to that question.

  • It does not matter they are both understood by the listener

  • It comes from a particular etymological history that makes one more correct than the other in the "simplest pattern" sense.

  • I should not be surprised to learn that someone already wrote up an explainer for this. πŸ˜›

    Grammar Guide: For Fuck's Sake vs. For Fuck Sake β€” wrong side of write

    It’s not that hard, for fuck’s sake. Wait. Is that right? I think so. I’m, like, 83% sure that’s right. We’ve all been there. We write or say something and then immediately begin to question our own reality. Let's get to the bottom of this fucker.

    @dgar it can be either as long as you start your email with, "I hope this email finds you well."
    @ryan2one3 @dgar and ends with β€œRespectfully,”
    @dgar @lisamelton the possessive form feels right. And gives you enough Ss for a decent exasperated hiss in the middle. I suppose it could be fucks’ sake instead of fuck's sake... depends how many fucks you give I guess…
    @dgar @hugo Understanding the joke, I’m nevertheless left to wonder what kind of sake kitsune prefer.

    Briefly though this might be suggesting some kind of Japanese rice wine endorsed by four out of four kitsune.

    @dgar It's the possessive, and it should be capitalized. In this context Fuck is the god of fucking. A "fucking damn" is the kind of damnation Fuck offers.
    @dgar fuck's sake, but with two Ss, one becomes silent 😎

    @dgar I just use:

    For the sake of Fuck.

    It can't be more professional than that.

    @dgar

    Definitely fuck's.

    Of course, in an official email, you should initially use the full term for clarity, and place "(FFS)" immediately afterwards. Thereafter, FFS will suffice. πŸ€”πŸ˜

    @dgar I'm retired from teaching, so I don't have to adjudicate on this shit anymore.
    @dgar "for love of all that is good and kind"

    @dgar
    I strongly recommend Margaret Atwood's hilarious story about how Fuck became a Divinity.

    In 'MaddAddam', the last book in the fab trilogy.

    @dgar The "s" on the end of "Fuck" is a genetive "s", and maybe also plural?

    So it's gotta be either "For fucks sake" or "For fucks' sake".
