Looking for tweets for nail one's colours to the mast.

reesetee To display one's opinions and beliefs; also, to show the intention of holding onto those beliefs until the end. The phrase originated with the practice, during nautical battles, to lower the ship's colors as a sign of submission. To nail the colors to the mast meant that you had no intention of submitting.
Technically, since the phrase originated in England, it's correct to use the British spelling of "colours." :-) Mar 12, 2008
