"Das" refers to "thats", while "Gey" refers to "gay". Use in a sentence where you forget to say "no homo", after the action that was extremely homo has passed.
Also used for a reaction to shitty memes.

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.
