Dirk – ‘d&rk (noun)
: a long straight-bladed dagger
When I was a wee bonnie lassie, I met a Highlander on the Isle of Skye. He was dressed in full Scottish regalia. He caught me glancing at the handle of his dirk, so he brought it out to show me. He taught me two important lessons which I shall never forget: One must never take it out without drawing blood, and that it slips very nicely between the third and fourth rib of ev’ry Englishman.
With that, he pricked his finger and tucked it back in his sock.
