Will this girl ever stop foreshadowing? In The Fame era she spoke about monsters, then she spoke about being born this way in The Fame and The Fame Monster era and in the Born This Way era she spoke about ArtPop.
Surely not as embarrassing as releasing an album titled 'Teenage Dream' at 25 years old?
Even though it's OT, the point of naming the album "TD" was because she wanted the album to make you feel euphoric, remember your first love and hopefully make you feel like you're experiencing it all over again. Basically the name consists on remembering your overall experiences as a teen that are worth having them present since once you grow up it's hard to recreate those. There's nothing wrong with that.
