Someone (mostly women over the age of 40) who is terrified of making left hand turns when driving. To avoid this fear, they will completely map out an entire alternate route consisting of only right turns, even if this means turning a 5 minute drive into a 45 minute labyrinth of hell.
husband:, I found a shortcut to get to our house faster, just turn left at ther next set of lights"
wife:"left turns are dangerous"
husband sighs and sinks back in his seat"You are such a left turn-aphobe"
