Sockdolager

~
Sockdolager: A huge blow that finishes a fight. John Wilkes Booth waited for that word (in the form of sockdologizing) to be spoken by an actor on stage. When the audience laughed loudly, he shot (sockdologized) Abraham Lincoln.

Also used to mean something very good, excellent. "That's a sockdolager of a knockwurst, meinherr."
