a crumb, piece of lint from kleenex, smalldry snot, or who's know's what that is stuck in one's nostril hair without them knowing of it hopefully. It is usually a disstraction to talk to someone with this condition especially while eating.
I almost kissed Sabrina during our first dinner date last night, except she had a major nosty going on and also some onion and garlic breath during dessert.
Remember when Glenn still had a head? That's nosty dude!!
You know what makes me nosty? Those old photos from high school when we had dreams and goals...
