What does pinheaded mean?
Pinheaded is an informal, disparaging English adjective for a person, idea, or action that is stupid, thoughtless, or conspicuously lacking sound judgment. Its figurative sense comes through the older idea of a “pinhead”: someone with an extremely small head. As a result, the word turns a literal physical metaphor into a quick judgment about foolishness, often in criticism of a plan, remark, or decision. The adjective appears in both British and American English and is usually hostile or dismissive rather than neutral. It can modify people, as in “a pinheaded theorist,” and abstract nouns such as decisions, proposals, and schemes. A much rarer literal sense means having a pin-shaped or very small head. Pinheaded is consequently vivid and memorable, but its bluntness makes it unsuitable for tactful prose.

Where does pinheaded come from?
The adjective is an English compound formed from pin, head, and the suffix -ed. Pinhead denotes a very small head and, figuratively, a person whose head is imagined as tiny. Pinheaded extended this physical image to describe foolish or thoughtless behavior. It follows a productive English pattern of head-based compounds, including emptyheaded and baldheaded, formed with the same head element and adjectival suffix.
