What kills boy germs?
Boy Germs are inexesistent germs often refered to when a person
(often a young girl) is around or in contact with a (often young)
boy. Boy Germs can be "passed" through contact or mere
presence.
Because they are inexistent, they cannot realistically be
killed. In a joking manner, some believe "Girl Germs" kill Boy
Germs, and Boy Germs can be washed away in a bath or toilet.
