Geeky Car Mods

A person who relates academic subjects to the real world outside of academic studies; for example, using multivariate calculus to determine how they should correctly optimize the dimensions of a pan to bake a cake.
A person who has chosen concentration rather than conformity; one who passionately pursues skill (especially technical skill) and imagination, not mainstream social acceptance.
A person with a devotion to something in a way that places him or her outside the mainstream. This could be due to the intensity, depth, or subject of their interest. This definition is very broad but because many of these interests have mainstream endorsement and acceptance, the inclusion of some genres as "geeky" is heavily debated. Persons have been labeled as or chosen to identify as physics geeks, mathematics geeks, engineering geeks, sci-fi geeks, computer geeks, various science geeks, movie and film geeks (cinephile), comic book geeks, theater geeks, history geeks, music geeks, art geeks, philosophy geeks, literature geeks, historical reenactment geeks, 2012 geeks, video game geeks, and roleplay geeks.
A more recent school of thought sees nerd as being a derogatory phrase, whilst geek is simply a description. It is taken to be someone who is an enthusiast, often in things outside of the mainstream spectrum. It may also describe immersion in a particular mainstream interest to an extreme that is beyond normalcy (e.g. sports geek). Of note is that in this definition, there is no reference to being socially inept in the slightest.
