Fun fact about the title: tribadism, tribbing, or scissoring, has the slang 「磨豆腐」pinyin: mò dòufu; lit. meaning: to grind tofu; meaning: to grind soybeans and make tofu in Chinese - possibly because of the former's resemblance of the latter's process and texture... I only say it once, don't ask me again [facepalm].
