Farmer's Hanky 

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's Hanky
