The flavors relate to the vocation of the particular geek. To start a code, a geek must declare himself or herself to be a geek. Some types of geeks deviate from the normal geek activities. This is encouraged as true geeks come from all walks of life. This is a popular vocation with new freshmen.
Geeks come in many different types of dress.
I tend to wear conservative dress such as a business suit. Most geeks identify themselves by their use of computers and computer networks. I use it when it serves my purpose. I play a mean game of Wing Commander and can use a word processor without resorting to the manual too often. I also know that when it says 'press any key to continue', I don't have to look for a key labeled 'ANY'.
