Torrent keywords (request/idea)

[nyfallioregn]

I was thinking, there are a lot of torrents. Both with and without a description. Hard to find specialties.
Main categories are to vague. What fetish?

What about a keyword system to explain contents of torrents? Like tickle, breath control, soft violence, etc.
This could also be edited after its been post. Like downloaders add main categories.
