I don't think you should copy other people's tags and descriptions exactly. YT hates this. Just find a lot of KWs that have to do with your video and use them as tags.
Then, make sure you choose a nice thumbnail and make up an exciting or shocking title that will capture people's attention.
Be creative, try to come up with something unique and weird. You want to choose a title that makes people want to click your vid no matter what. DOn't say "Lady Gaga naked pics!" Everyone uses that.
Try: "Pictures of Lady Gaga's used tampons!" Or something like that.
I hope this helps.
