the inferior "earpiece" on your headphone set. for songs that use surround sound, where some sounds are only in one earphone but not the other. there is always one earphone that gets all the sounds, this is the superior earphone, the other earphone only gets some of the sounds. this is the bitch earphone.

it is vitally important when listening to an ipod/walkman etc with only 1 earphone in, that you dont put in the "bitch earphone"

Referring to women who are sexually or romantically attracted to other women. Applies to both lesbians and bisexual women, as it is only the same-sex attraction that matters, not any other attractions the women may have.

Originates from the Greek poet Sappho, a bisexual woman from the Isle of Lesbos, from which we get the term lesbian.
