What does oddball mean?
An oddball is a person who behaves or thinks in an eccentric, unconventional, or unexpected way. The word is informal and often conveys mild affection, amusement, or surprise, as in the familiar description of someone as “a bit of an oddball,” although it can also be dismissive when used mockingly. In its broader sense, oddball may refer to any unusual thing, idea, or event: an unexpected decision can be described as an oddball choice, and an unconventional result can be called an oddball. The term is especially common in British and American informal English and often suggests that someone or something is harmless but does not conform to familiar patterns. It is more affectionate than the harsher words sometimes used for eccentric people, making it useful for describing colourful personalities, unusual habits, and eccentric creativity without requiring full approval or understanding of the person concerned.

Where does oddball come from?
The word was formed in English by combining “odd” with “ball,” following the older use of “ball” in compounds referring to a person, often with an implication of strangeness or unlikeliness. The expression was established by the early twentieth century for an unconventional person and was later extended to unusual objects, ideas, and events. Its modern meaning also reflects the older sense of “odd” as strange or irregular.
How oddball is actually used
