and those would be what, exactly?

There is a song that is currently getting a lot of play on the pop music radio stations here. I hear it in taxicabs, in shops, and today while I was getting a haircut. The singer, or rather shouter, of this song definitely sounds American. During the course of the song she details her considerable physical charms and punctuates the litany of self-praise with phrases like "you spendin' all you money on me."

I give you the refrain of this song, verbatim:

My hump.
My hump, my hump, my hump.
My hump, my hump, my hump.
My lovely lady lumps.
