I don't believe anyone here has said a "farmer blow" is never appropriate. You'd get a helluva frown doing it at the dinner table though. Likewise wiping your nose with your sleeve. Times and places, BGG. And while I'm at it, who is more likely to carry a pack of tissues: a woman or a man?
You could prove your troglodytic manhood by just letting it drip unimpeded. You might even enjoy it as a condiment on your sandwich.
