electioneering,
I respectfully disagree. A party piece is something someone does as a stunt or act to entertain others in a party atmosphere. Something as simple as a good joke, or being able to play the guitar or do the splits. It's some superficial act used to entertain people.
In this song, his party piece is him pretending to enjoy the relationship and acting like there's nothing wrong. However, he starts to let go of his party piece... i.e. he can be his true self and shatter the illusion he has created for everyone else that his relationship is a happy one.
