Used to signify foolishness/disapproval of ones action.

Spoken as "day" but with a slightly pro-longed ending, in a deep 'retarded' sounding accent.

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.
