Hmmm. Well, what you're describing is something like a gas-huffer, really! But I guess you're also describing something like a Midas touch -- take all the ugliness and all the generally-badness (this includes cliche as much as it includes vomit) and turn it into PARTY. All signs point to party, become a feature of that party. Where most people have a party, Ke$ha seems to be in possession (or in the jaws of) a PARTY MONSTER.

So inadvertently (I presume) her generic title takes on an interesting meaning -- the party itself (not Ke$ha) is the wild animal. She's the hapless person who thinks she's controlling the damn thing, without realizing that being carried in its jaws is not necessarily the same thing as riding it.
