Chocolate Handcuffs

The act of "popping" ones ball or balls (depending on elasticity) into one's partner anus and then requesting for them to clench. Once restrained in this manner the only "key" is a good push hopefully not dislodging any foreign matter other than your testicle/s

"Man why are you walkin funny?"
"That chick at the cafe we saw yesterday didn't want to let me go so she restrained me with her chocolate handcuffs! I'm gunna be out of action for a few days."
