A "geek" in street terms or around drug dealers and users means that the person who is a "geek" is a very bad drug addict. Someone who will do anything for drugs. Not unlike a "crackhead", "cluck", or "dope fein"

A fucking amazing person who has to put up with people calling them a socially helarious name because they like things that are deemed “un-cool” in today’s society.

Someone who has the passion and drive to be the most knowledgeable in their chosen field ,
This trait will not need nurturing as it is a natural response for the love of the subject

A geek is a 2005 way of calling someone a nerd, you usually call someone a geek if they're wearing glasses

The chinese version of a nerd

A geek is someone who has an advanced knowledge and interest of the video game universe and/or the internet trends. A gamer can seem like the same thing, but in fact, the gamer is only invested in his own games and has little to no knowledge regarding others types of gaming platforms. Not to be confused either with the nerd who is great at school and well implicated in his studies and the pursuit of a big career.
