When a woman/man is giving oral sex to a man, and his scrotum, at any point, rests on the nose of said person.
She said it was not the nostricle that choked her up, but, in fact, the smell.

A spontaneous freezing of the effluvium within a persons nose when inhaling in sub arctic temperatures. Frozen mucus within the nasal cavity in when the mercury is reading minus anything.
It was -10 in Chicago's loop and nostricles were forming in my nose as I walked to the El train.
