  • "Be a good boy

    Push a little farther now

    That wasn't fast enough

    To make us happy

    We'll love you just the way you are

    if you're perfect"

  • I love Alanis's lyrics.

  • Since when is "bisexual" a synonym for "perfect"? That listing is bizarre.

    Can you imagine exclaiming "Oh! Bisexual!" every time something is perfect?

    April 12, 2011

  • You're looking at a list of definitions, not synonyms. And yes, I can actually imagine exclaiming "Oh! Bisexual!" every time something is perfect. I think it would be funny - although I'm sure the novelty would wear off.

    April 12, 2011

  • I can see problems. Like a gymnast coming in with a bisexual 10 on the pommel horse and then being disqualified under gender rules.

    April 13, 2011

  • I think it refers to bisexual in a botanical sense, i.e. monœcious.

    April 13, 2011

  • Used in the Same Context

    Time · accidental · active · aorist · beautiful · cattle · certainty

  • For another example, see ulna.

  • Anyone else notice how the word 'perfect' is taking over the world? Instead of yes, ok, thanks, or any acknowledgement of any kind, the answer is now 'perfect'. A luxury hotel chain needs to trademark this word immediately.

    May 21, 2011

  • On a positive note, the use of absolutely in such contexts appears to have withered.

    May 22, 2011

  • But do people now say "Per-fuckin-fect!"?

    *not sorry that I'm a little out of it*

    May 22, 2011

  • There's an unwritten rule in English that when you insert an expletive into another word, it must precede a stressed syllable. So, for example, you can talk about "Phila-fuckin'-delphia", because "del" is a stressed syllable, but you cannot talk about "Philadel-fuckin'-phia", because "phi" is not a stressed syllable.

    So "Per-fuckin'-fect" is out. I think the closest permissible equivalent is "Fuckin' perfect!", which I do hear occasionally.

    May 22, 2011

  • But "Per-fuckin-fection!" might work, eh? Note the nice alliteration.

    May 22, 2011

  • I'm worried that people who are writing down unwritten rules are breaking an unwritten rule that unwritten rules should not be written.

    May 22, 2011

  • unrite of unright unwrite?? and its (positive and negative) variations, combinations and permutations. i.e. rite of right write

    May 22, 2011

  • Bilby beat me to my comment. Also, shouldn't that be per-pfucking-pfection?

    May 22, 2011

  • Foxy, that sounds like something Sylvester the Cat might say (or I am thinking of Daffy Duck?).

    *wonders if Fox is brushing up on his Deutsch*

    May 22, 2011

  • Wow, pterodactyl, that's true! You can say "fan-fucking-tastic" but "marv-fucking-elous" sounds weird.

    May 22, 2011

  • You meant 'fan-fucking' right?

    May 22, 2011

  • "A luxury hotel chain needs to trademark this word immediately. "

    As in:

    Are you one of the power elite? Then think of the Sofitel Manhattan. Perfect for your next intimate rendezvous.
