pinheaded
Lacking mental sharpness
Pinheaded is an informal insult meaning stupid or foolish, suggesting someone has a head so small there's barely room for a brain.
It's the adjective form of pinhead, which can describe either a literal pin's head or a person of limited intelligence.
Don't be so pinheaded—read the instructions first.
The term carries a dismissive, contemptuous tone and is more colorful than simply calling someone dumb.
