I recently got my grubby little hands on one of fall out boy’s hidden tracks, Pavlove, from Folie à Deux.
BUT: I read probably way too far into it and i think i figured the title out. Stick with me little chicken mcnuggets you’re in for a ride.
So, Pavlov’s Dog was an experiment. Pavlov trained his dog using a bell and the dog’s food. Each time food was served to the dog, he rang the bell. After enough time the dog associated the ringing of the bell with food, and would salivate even if no food was present. This is known as classical conditioning.
SO the title is a combination of ‘Pavlov’ and 'Love’, the title must mean that the subject of the song/ title is someone who is being classically conditioned to love someone or something. It’s pretty sad when you think about it. Someone was being forced to love something
Disclaimer: I tend to read into things and i could be totally wrong
