Originally derived from the movie Thirteen Days, the term “Code 13” has numerous definitions:

1. This information, of or relating to political strategy, is meant to be kept top secret, private, and on the downlow.
2. Privileged information.

Then being applied by prestigious members of the Warren Mott High School elite, in Warren, Michigan, the code took on an underground meaning as well:

3. The motorcade formation of vehicles traveling to various locations as a group confidentially.

The group is recognizable by their high speed driving in uniquely equipped American-made vehicles, with chrome “13” emblems, through residential areas, highways, and school parking lots. Certain political affiliations allow the financially sufficient and resourceful brotherhood to remain elusive and ambiguous.
