The Academy of the Holy Cross' mascott with two different meanings:

1. A female warrior (even though the picture on the WCAC sign in all the WCAC schools is of a male warrior)

2. Plaid cloth

-or if you're a cool kid-
3. A female warrior dressed in plaid
Even though it isn't the best mascott, the AHC Tartans are better than you!

A two dimensional human-readable bar code symbology with hundreds of combinations per module. Usually found on Scottish things such as kilts, ribbons, sarongs, and bagpipes. Each clan (a Scottish family, spelled with a C) has its own tartan.
Hamish the red got away with sending the HD-DVD key by way of tartans on kilts in the mail.

The tartan was found on kilts early in the Faerytale Era.
