Definition
"Lumpy" describes something that is uneven and has bumps or lumps on its surface or within its structure. Imagine mashed potatoes that weren't mixed well or a mattress with springs poking through. It is the opposite of smooth and uniform. "Lumpy" can describe both physical textures and abstract concepts, like a lumpy plot in a story. Unlike a perfectly flat surface, a lumpy one has irregularities. It often implies a lack of refinement or care in preparation.
