Hello Suki, The "tom tom dance" is a danse The expression is an onomatopoeia, "hubba hubba" is slang and means "fantastic" or like " hurrah!" ...

tom tom dance; www.youtube.com/watch?v=qP7lUlVFu9U - hub·ba-hub·ba (hb-hb) is a slang term. Used to express approval, pleasure, or excitement. eg look at that guy, he's so gorgeous, hubba, hubba!

I imagine it has to do with the Tom Tom Club (not the music group), which you can read about here: http://en.wikipedia.org/wiki/Tom_Tom_Club And "habba babba" is a silly phrase. And also the theme of some silly videos that you must see to believe: http://www.youtube.com/watch?v=jrK7CZos404 It reminds me of one of my favorite Bubble gums, called "Hubba Bubba Bubble Gum".
