When something is "sticking out," it means it's projecting or protruding from a surface, making it noticeable. It implies that the object is extending beyond its surroundings and is easily visible. Think of a sore thumb that's "sticking out" from your hand, or a flag that's "sticking out" from a building. It's all about standing out, both literally and figuratively. It usually creates asymmetry or interrupts the normal flow of things.
