lame brains

Not very bright

Lame brains is a mild insult for stupid or foolish people: Those lame brains left the gate open and the dog got out.

The singular lamebrain works as both noun and adjective: a lamebrain idea.

The term suggests incompetence rather than malice—more eye-roll than genuine offense.
