A tattoo, typically placed on the lower back region, depicting the San Francisco Giants 2010 World Series Championship win. Commonly found on middle-aged men, the tattoo typically is usually associated with mild obesity and hairy backs. Typical reactions to the champ stamp include, but are not limited too, drunken embracements, high fives, and/or illusions of the men convincing themselves they actually had something to do with the victory
