Ever found out lyrics for a song you like that totally change the meaning of the song? I have. It doesn't take a genius to figure out what this song is about, just read the lyrics. Oh iosys, how I love you sometimes.
This song didn't have to be subtle, but it's hilarious how they tried to be. And failed. I think "fountain", "firework", "gun", "mega flare", and "giga flare" were all used to describe the same thing... This song loves that topic. Fisting has actually been proven to damage your rectum if done incorrectly. So it's more like "damage", unless being damaged is a surprise. "Words". If you're blowing words, then you're doing it wrong. And I now pronounce this girl as "the anti health teacher."
Pretty sure the part when she holds her hand up in the air and refers to sucking on something till it fountains would be hard to be a troll sub though :p Edit: Oh, and the part with the use your hands and explore them everywhere, they move their hands all over their body, so it'd be hard to make that a troll sub.
