post turtle
n.— «Out here in the country, Bush and his buddies are referred to as “post turtles.” Those are turtles you might see on the top of a fence post. They don’t know how they got up there, they don’t know what they’re doing there, and they don’t know how to get down.» —“Post Turtle Bush” Charlie Averill (Knox, Indiana) May 15, 2006.
