Sophomoric humor is the kind of silly and childish jokes that are often made by people who are around 15 or 16 years old. This humor usually involves making fun of bodily functions or other things that are considered immature by grown-ups. Some examples of sophomoric humor might include jokes about farting, burping, or other bodily noises. However, while this type of humor might seem silly or immature to adults, it is often seen as funny by teenagers who are still learning about the world and figuring out what is considered socially acceptable.
