Beanbrain is an informal, mildly derogatory term for a stupid or dim-witted person. It joins a long tradition of 'small thing + brain' compound insults (pea-brain, bird-brain) implying the subject's head is occupied by something inconsequentially tiny rather than a proper brain. The register is more comic than vicious — it is the kind of insult used between friends or in light-hearted ribbing rather than serious attacks.

I can't believe the beanbrain forgot to save his work before the computer crashed.
Origin: Compound insult: 'bean' (a small, trivial object) + 'brain' (intelligence); follows the established English pattern of 'small-object + brain' insult compounds. Editorial expansion authored on Slangora.

A mild derogatory slang term for a stupid or dim-witted person. The bean implies the brain is small, hard, and not particularly functional. Belongs to the category of playful insults where the comedy softens the blow — it is more affectionate mockery than genuine contempt. Common in British and American casual speech, often directed at someone making an obvious mistake.
