rawrcannon 

invented by Nicholas Fennema on April 7th, 2009 with inspiration from rotflcopters and rotflknives

when all else (except everything NOT categorized as "brute-force") fails, people turn to the rawrcannon, the artificial shoop-da-woop laser made by the aliens working for the Pope, working for the government, working for the last (deceased) Pope

Rapecannon 

A large, highly destructive weapon or force. Something that basically owns the hell out of anything it goes up against.

Also, something so insanely awesome, it blows everything else away.

"This gun is such a rapecannon, I killed everyone on the map with one shot".

"That band is so rapecannon, I don't know why you would ever listen to anything else".
