It's a hundred dollar bill idiot.

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.

In drug culture, blue dollars are single bills that were used to snort adderall or amphetamines. Generic Adderall comes in very distinct deep blue divisible tablets that are easily crushed and snorted for a quick high. The blue pigment stains basically everything it touches, so the edges of these bills are left with a faint blue pigment after adderall/amphetamine insufflation. This is get another easy way to spot a fellow speedster.

A dollar manufactured only by the "blue dollar guy". Has something to do with red pants.
