A girl who often has an extremely high-pitched voice. No, not a naturally high voice, a voice that legitmately resembles that of someone who has just inhaled at least half a tank of helium. In addition to their high and annoying voices, they also possess many characteristics of the common "bitch". Helium bitches are also typically very arrogant and believe themselves to be quite intelligent when really they possess the IQ of a rock.
