1 definition by non-dingbat

a term used to describe a person (often a woman) who does not think before acting and most times acts on pure impulse.
Some start off intellectually or emotionally retarted which eventually leads to being a dingbat. Others are born that way and are cursed with being a dingbat for life.
ex: I dated some real dumb chicks, but that Courtney girl was the biggest "dingbat" I ever encountered.
