Wewt, I stumped GOOGLE!
Anyways, it's a song called Heart Tits from a little known band known as The Grammar Club. I'm not surprised google didn't have it though.. the only way you can see their lyrics is pretty much on the pictures they've put them on that come with their EP XD.
Here's a link to their EP, which is probably the only place you can hear the song. (and yes it's a legitimate download... you aren't pirating it, they put their own EP up for FREE.)
