What's the deal with the kupaa tag? The wiki simply says that it's Japanese onomatopoeia for spreading something, but people are adding it to posts where there are no onomatopoeia at all (e.g. post #2477135, post #2444807, post #2439921). Isn't spread_pussy sufficient?
Looking at the pictures tagged kupaa, it seems that the tag is being used for the specific case where people are spreading a pussy (or something else, e.g. post #2348374) with their hands. I'd recommend spreading_pussy, spreading_cleavage or the generic spreading as a less cryptic alternative for that usage, if we want to adopt it officially.
