Snotty Boy, better known as Eugene Beady, is the secondary antagonist of Back at the Barnyard. He is Mrs. and Mr. Beady's nephew. 

Snotty Boy is mean, dim-witted, mean-sprited, sadistic, abusive, annoying, spoiled and obnoxious. Snotty Boy constantly boasts and arrogantly brags about having "skills" that he clearly doesn't have (such as possessing Karate skills, psychic abilities, insults, and salsa dance moves). He annoys everyone, except Mrs. Beady, whom he acts sweet and innocently to until she is out of earshot. Snotty Boy's range of insults is rather limited and unimaginative, usually just resorting to "stinky," "stupid," or other basic insults.
