Proper Noun: 1. A song made by System Of a Down, featured on the album Steal This Album! This song focuses on how completely retarded war is, and has a music video made of it that included footage from the February 15, 2003 Anti-War Protests that Michael Moore helped out in making. The song includes lines about how many children die of starvation while we blow the money that could have been used to feed them on making bombs that will only kill more people and how politicians keep up false images. An extremely good song.
1. Every time you drop the bomb you kill the god your child has born...Boom! Boom! Boom! Boom!
BOOM! is a collection of awesome people. Usually great for a bowling team name. Everyone wants to hang out with them and be around them. They are outgoing, well liked, and all around amazing. Whenever they do something fantastic, people yell "BOOM!" and high-fives usually follow.
