To me a “geek” is someone who is intensely passionate about a particular thing. For the average person “geekiness” revolves around something technical, but for me a “geek” can be a “music geek”, “sports geek”, “math geek”, “history geek” or almost any type of person passionate about some topic. A geek, however, usually is normal in other ways. They have interest in dating, friends, family. They have social skills, which involves talking and laughing. They have a “look”, whether it be punk, classic, “comfortable”, or whatever. And often their geekiness in a particular topic overflows into other areas.
