When a guy who always denied ever jacking off first proclaims to their friends that they indeed do masterbate. Usually admitted after days, months and years of questioning and teasing.

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.
