Having sex with a girl where you stick one foot in her mouth and one foot in her ass, next you eating out her vagina that is infested with crabs and/or is yeast infected.

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.
