What does lamebrained mean?
Lamebrained is an informal adjective describing a person, idea, plan, or remark as foolish, silly, or deficient in good judgment. Its tone is usually teasing or contemptuous rather than carefully formal, suggesting that the fault is obvious and perhaps even amusing. A “lamebrained idea” is an idea that is poorly planned or implausible, while a “lamebrained scheme” is often an impractical or ill-conceived scheme. The expression can describe a person as thoughtless or unintelligent, although it is generally milder and less direct than saying someone is stupid. Once common in informal North American English, it now sounds somewhat dated, and many speakers use alternatives such as foolish, silly, or ill-conceived. Even so, it remains vivid because it evokes someone acting without the common sense supposedly supplied by the brain.

Where does lamebrained come from?
Lamebrained was formed in the late 19th century by combining “lame” with “brain” or “brained,” following the older pattern of the compound noun “lame-brain.” The expression was particularly associated with informal North American usage. Its meaning developed from the older sense of a weak or ineffective brain to the modern figurative sense of foolishness or poor judgment.
