A type of cocktail drunk as a test of courage by members of a brass band. It is made typically by taking one shot of every spirit available behind the bar into a pint glass, and then topping it up with a mixture of lager and cider ('snakebite').
Occasionally, it is used to fill trophy cups after a major contest victory.
The act of blowing your nose by a combination of covering one nostril with a finger and clearing the other with a powerful nasal blast of air, for use when a suitable snot receptacle isn't available. Popluar with farmers and footballers and useful in the right situation, but not really acceptable among polite company. Unless you're desperate of course.
Look away love, I'm going to have to do a Farmer'sHanky
The process of clearing ones nose without the assistance of tissues, hankies etc etc
More specifically, clearing ones nose by pushing one nostril down with the index finger and blowing out of opened nostril, subsequently shooting snot straight to the ground. The bushman's hanky must be executed with a fair level of pressure or the snot will end up smeared or 'looped' around the nostril (it may even lodge somewhere on the lower cheek or mouth region) rather than on the ground where it belongs.
