"Twerp" is an informal expression used to refer to a silly or annoying person. It's meant to be derogatory and is a bit of an outdated term. Team Rocket here has used it to describe Ash and his friends, who they find annoying. Ex: The school bully is such a twerp. He stole my lunch money today. Ex: Ash and his twerp friends foiled our plans once again! We'll get Pikachu one day!
