Limey: a deregatory term? Not at all! According to Wikipedia (which is always right, right?)... "In 1749, the Scottish surgeon James Lind discovered that citrus foods helped prevent scurvy , a particularly deadly disease in which collagen is not properly formed, causing poor wound healing, bleeding of the gums , severe pain, and death. [ 5 ] In 1753, Lind published his Treatise on the Scurvy , which recommended using lemons and limes to avoid scurvy , which was adopted by the British Royal Navy . This led to the nickname Limey for sailors of that organization." Blimey! Speaking of which, the term 'Blimey' is a euphimism derived from the phrase 'god blind me'.
