Etymology: "Humper" is a straightforward formation: it combines "hump," a word for a rounded protrusion or lump, with the suffix "-er," which turns a verb or noun into a word for someone or something that performs an action or has a particular quality. Put together, the term describes whatever hump-shaped thing or hump-related action it names, and the construction follows a pattern English uses widely, such as "rider" from "ride" or "teacher" from "teach."
