One who wants to ram their fist down (or up) society. More generally: liberals, socialists, and communists that hold their fists up.

The opposite of Teabaggers.
1) Why don't those Fisters have their own rally instead of disrupting the Teabaggers' rally?

2) I went to the store to buy a fur coat, but the store was totally picketed by Fisters. I couldn't get past them.

When you get raped by Doug Fister. Since being fisted destroys that region, being fistered is also destructive. If you have ever been fisted or seen someone fisted, you understand what I mean. He who has been Fistered has been utterly defeated, such as the 2011 New York Yankees.
The Yankees thought they would advance to the ALCS without Verlander on the bump for the Tigers, but they were Fistered by Dougie Fresh.
