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. For those geeks that can do anything and everything. GAT usually precludes the use of other vocational descriptors.
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'.
