"Several traffic signals around the county seem to be less intuitive than others, judging by some of the mail the Doc receives. One that regularly flummoxes drivers is on northbound Seminole Boulevard at the intersection of Ulmerton Road." Lorrie Lykins, St. Petersburg Times (Florida), November 14, 2010
About the Word:
No one is completely sure where the word flummox comes from, but we do know that its first known use is found in Charles Dickens' 1837 novel The Pickwick Papers and that it had become quite common in both British and American English by the end of the 19th century.
One theory expressed by some etymologists is that it was influenced by flummock, a word of English dialectical origin used to refer to a clumsy person. This flummock may also be the source of the word lummox, which also means "a clumsy person."
