When performing fellatio and a hair, generally a pubic hair, enters the fallatiater's mouth. Occasionally the hair will get snagged between the victim's teeth causing significant irritation. Another typical scenario includes the hair sticking to the tongue, often precipitating a half-cough/half-gag reaction similar to a cat coughing up a hair ball.
