Meaning of 'jiggelin' - word from the song 'Policeman' of Eva Simons

I think that jiggelin' is a contraction of "jiggling buttocks" - "jiggling" being similar in meaning to "wobbling".

http://www.thefreedictionary.com/jiggling

 To move or rock lightly up and down or to and fro in an unsteady, jerky manner

So, the speaker is saying that she simply wants to lower her jiggling backside (or perhaps her jiggling body as a whole) towards the floor (eg the dance floor of a nightclub), presumably as a dance move - ie, that she simply wants to go dancing.

She is finding the conversation with the policeman frustrating, as it is preventing her from reaching the aforementioned night club, where she can proceed with the "jiggelin'".
