Lyric discussion by Slayton 

I think that many of the above posters were right in that it is a musing on how the most important things in life are never taught. "Loveology", "Stayology", "Pleaseology", "I'm-Sorryology", "Forgive-Meology", "Kissology" - how to cope in a relationship, "Busology", "Planeology", "Trainology" - how to move through your life easily, "Mamaology", "Papaology" - how to be part of a family, "Meology", "Youology" - how to develop your own identity and/or what it MEANS to have an identity, and "Porcupineology" and "Antlerology" - discreet metaphors for sex. Using these 'euphemisms' for sex may also be a jibe at how the education system balks at the prospect of sex education.

Alternatively, or maybe simultaneously, I can read it as someone trying to apologize to their partner, trying to beseech them to stay with them and forgive them, but the person is too scared or too insecure to let all these feelings out at once so they disguise them in the midst of a stream of miscellaneous babble.

"Open up your textbooks", "Let's study class" are saying that the 'narrator' is learning about these things through experience.
