(noun) To masturbate vigorously, while putting 3 fingers in your anus. More than 3 fingers do not constitute a fassbender.

This type of masturbation tries to explain the sexual conflict Michael Fassbender put himself into in the movie "Shame", as he engaged intercourse with both male and female partners.
1. "After that girl rejected me, I went home and had a fassbender, while I was crying and eating ice cream."

2. "Hey guys! Let's watch The Expendables and have multiple fassbenders!"
