Most rap, you enjoy already? Mazel tov. It's also used in other
dialectical forms of English, but you won't hear such constructions
employed in standard English.

Try writing it out and see if you can get a sentence that's parsable by
a human. Alternatively you could stop treating English legalistically,
and throw up a style warning for formations that aren't clear and
straightforward. That would leave the onus on the writer to accept or
reject the advice.
