Describes the moment where a male'
s voice cracks, especially with strain such as with shouting. The voice pitch suddenly rises and the contrast with the normal deep voice makes it
sound like a squeak or '
pop'.
Especially used to describe teenage boys who are undergoing voice deepening during puberty; where vocal cords lengthen and thicken in response to testosterone from the testes. (Hence the use of the word 'teste' and '
pop'.) However, this term can be used to refer to young adult
men as well.
