Party Piece 

Some exhibition of talent specifically used to entertain at gatherings. Often some goofy impersonation or a strange talent, but may be as broad as a favorite song or poem.

My brother's party piece is his ability to wiggle his ears; mine is singing "Getting Married Today" at lightning speed.

Appears in the lyrics for Disintegration, by the cure. I can guess what it means, but really have no idea. "Firm" ideas anyone?

"...
oh i miss the kiss of treachery the aching kiss before i feed the stench of a love for a younger meat and the sound that it makes when it cuts in deep the holding up on bended knees the addiction of duplicities as bit by bit it starts the need to just let go my party piece ..."

I've seen it translated in the context of The Cure "Disintegration" song as "a partner". Translation by polish journalist Tomasz Beksinski.

"...it starts the need to just let go my party piece" means - to let go (resign) of my girlfriend (a partner)
