The Sipan Flu is a made-up disease and codename used by people who can't make it into work the next day because they're busted from having been worked over on all fours the night before. In other words, their ass hurts too much to move.

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.
