Polish fiddle 

A solo sex act in which a lady tittie-fucks herself with a dildo. (Orig. Only a Polish woman would be dumb enough to tittie fuck herself with a dildo. Also, the act of tittie-fucking oneself with a dildo would produce a motion much like bowing a violin).

Susie Woznoski: "My god- my neck is so sore."
Dana: "Why?"
Susie Woznoski: "I tried the Polish fiddle last night. I did it for hours and never came." :(
