In a mile-ago thread I noted that I was retiring to think of salacious headings for an innocuous thread ... and here it is!

Cock-up is defined as a muddle in the OED-CD.

It's a phrase of British origin I believe. (Always did have a way with words, them Brits!)

Then, following SOED directions, I looked up cock and there are several definitions that run on and on and on.

Well, now that I have your attention and you have LIU .... comments?
