A holiday celebrated in the USA on Election Tuesday each year. It commemorates all the hard working engineers that wear polo shirts on a daily basis, but are still asked from time to time by their tie-wearing bosses to put on a tie in order to meet with a customer. It is customary for engineers to wear a polo-style shirt, buttoned all the way up, and an accompanying neck tie on this day. It has widespread observation in the states of Michigan and Virginia.
Dude, don't forget to wear your polo tie for Polo Tie Tuesday tomorrow!
Oh yea, and don't mind the funny looks you get at the election polling place!
