Also, a kick in the teeth. A humiliating setback or rebuff. For example, That rejection was a real kick in the pants, or That review was a kick in the teeth. A third, vulgar variant of these colloquial terms is a kick in the ass. Versions of this last expression— kick in the breech, kick in the behind—have been used since the early 1800s.
