noseballs
A fabled term thought to be impossible by many; when a couple ar 69ing, the female (or male, if you like to be gay), sucking on the guy's penis, deep throats him so much she panicks and attempts to take a huge sniff of air so powerful that she (or he, you sick bastard) sucks his balls up into her (I'm not saying "his" anymore) nostrils, causing intense pain to both people.
