The terms "nerd" and "geek" are often used interchangeably, but they are not the same.
A "nerd" is someone with an extremely intense interest or fascination in an intellectual field of study (often an obscure field). Being a nerd is typically associated with intellect, as they often enjoy specializing in complicated fields of study. Nerds may also have difficulties socializing with others, as they may border on being classified as a "genius".
An alternative definition is that a nerd is often, but not by definition, very intelligent, and has "skillz," spelled with a "z" to indicate that the skill set is uncommon, or perhaps impractical. This may cover a broad range of interests, from movies, to games (video and table-top), to more practical skills such as computer science.
A "geek" is someone with an obscure interest or lifestyle, but not necessarily an academic one. For instance, Star Trek, World of Warcraft, or anything that requires a vivid imagination are typical areas of interest. Geeks can vary in their interests, from fun and sometimes even frivolous things, to heavy technological influences. An alternative definition of "geek" is someone who is a nerd without "skillz."
REMEMBER: Someone who calls themselves a nerd or geek may have different definitions of one or both, or completely different or mixed definitions. These tend to vary regionally, but with variation by person as well. Furthermore, it is possible for someone to be a nerd and a geek, depending on definition. For example, people who like Star Trek may be interested in NASA level quantum physics. Star Wars fans may know everything about laser weaponry. Think about it - these kinda go together. Often being a geek leads to being a nerd, as people research areas of science and technology appropriate to their interest. Similarly, nerds can become geeks, as the obscure interest could be a prime example of their particular field of expertise.
Observe the person. Do they recite lines from "Monty Python" shows or movies, or do they occasionally throw Latin words into their dialog? Nerds are not as concerned about their level of trivial knowledge as geeks are known for embracing. Geeks often take interest in the more obscure, trivial details of life, such as noticing that your present situation is much like one from a cult-classic book or movie. Nerds will seemingly be uninterested in the details of daily life, and more focused on fantastic, scientific possibilities and the future of mankind.
Take a quick inventory of their prominent possessions, especially ones related to hobbies and other interests. Check for unusual objects, such as a dictionary of an obscure language, or a shelf full of anime figures. Nerds may be more willing than geeks to show off hobbies and possessions that flaunt their intellect, where as geeks may take pride in more obscure and unique subjects.
Engage the person in conversation. If the person fails to respond in a socially comfortable manner (ie: they make you nervous, or vice versa), you may be talking to a nerd. If they respond in a comfortable manner but appear a little 'dorky', include obscure references, and/or act silly, you might be talking to a geek. Also, nerds may speak in layman's terms for your benefit because you may not understand the basic concepts of their area interest. Geeks may speak in detail about their own interests, unconcerned with whether or not you truly comprehend it.
Inquire about the person's interests. Hobbies involving Calculus, Quantum Physics, and other theoretical sciences are good indications of a nerd, while an obsession with Japanese Manga or some form of technology puts them in line with a geek.
