blond moment(redirected from a blonde moment)
An action that is unintelligent, forgetful, strange, or foolish. The use of "blond" comes from the stereotype that people with blond hair are not as smart. For that reason, it can be considered somewhat derogatory. I thought Mom knew Joe's phone number, but she's having a blond moment and can't remember it either.
