  • This word sounds suspiciously like co-op.

  • But it actually is a word. In fact it's one of those that, since frequently misused along with co-op, drives me completely batshit.

    December 28, 2008

  • Ooooh, I have genuinely never heard this word confused with co-op; is that the misuse which vexes you so, or something else?

    December 29, 2008

  • The misuse, definitely.

    December 29, 2008

  • I meant is it that particular misuse, or a different one!

    December 29, 2008

  • I'm a member of the Co-op. Uhh, voluntarily.

    December 29, 2008
