When a person annoys you and you want to annoy him too so you say "Nana Banana". It's like saying "I'm not listening" or "You can't catch me". It is oftenly said in a game of Catch/Hide and seek
Someone: you got a ticket to the movies? This movie sucks!
Me: jealous much? Nana Banana

Its stronger than your mom gay, ur dad lesbian, ur granny tranny and your sister a mister all togehter, you can use it to obliterate someones existence as well as the unviersal space time continuum.
