the process of masturbating immediately after your hand/arm has become numb either naturally, from a shot, or from sitting on your hand on purpose. Its main purpose is to make it feel like you're not jacking off by yourself in a dark room watching a porno that you've already seen dozens of times.

Also mentioned on the Comedy Central tv show, "Ugly Americans"

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.
