The stuff that sticks to your hand after you have had it in a nasty dirty boat bilge. A mixture of soap scum, sewage and oil or other skanky shit found in a bilge

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.
