Crazy Space Incest. Term commonly used in fanfiction.
Refers to a romantic/sexual relationship between the characters Simon and River Tam on the show Firefly.
Many viewers of the show felt that there was a romantic, if not sexual, subtext between Simon and River thoughout the series, thus the term CSI, crazy space incest, erupted.
Person 1: I read a Firefly fic yesterday and it had some CSI parts in it. Do you want me to send you the link?
Person 2: Yeah, cool. I love CSI fics.

CSI stands for "Crime Scene Investigation," which as the name implies are a group of individuals, usually forensic scientists, within a police force who examine and process a crime scene and the evidence found there. It is also a show on CBS with reruns on SpikeTV. There are three forms of the show: CSI, CSI: Miami, and CSI: New York. Many claim that CSI is CBS's stylized response to the show Law & Order on NBC. However, the television show is just a glamorized, more "viewer friendly" view of the real CSI job.
(Taken from www.vgcats.com) "In the normal world, CSI, or Crime Scene Investigators, collect and analyze information on a crime. Their findings are then passed on to the detectives and other authorities as the criminal case makes its way down the system. However, in TV, show the CSI investigators take on nearly all aspects of the case. Even arresting and interviewig suspects. Making them some sort of Judge Dredd enforcement officer. A complete package of Judge, Jury, and Executer."
Although I like CSI and Law & Order, I personally prefer Law & Order because it's more realistic. Also, since I'm pre-law, I was upset with the court scenes on CSI.

A rather overrated tv show that someone lots of people like despite having the shallowest plotlines of any television. The average episode is like this: Someone dies, Crime scene people examine the corpse, someone makes a witty remark about the death, they find some suspects, they interrogate the person with the same dialogue they used the previous episode, the person admits to somehow not kill-but-in-the-same-time killed the person, then they find the real culprit and rinse and repeat for 12 fucking straight seasons! Honestly, how can a show last for 12 years using the same copy paste story every single goddamn episode!

Says a lot of the American public tbh. Meanwhile, clever shows like The Wire get lots of praise but low ratings (show only lasted for 5 seasons compared to CSI who lasted for 12!) and get canceled after a few years of airing due to the dumb masses wanted to watch stupid recycled crap instead of clever and informative tv. To quote Fry from Futurama: "But that's not why people watch TV. Clever things make people feel stupid, and unexpected things make them feel scared."
A typical episode of CSI:
A body is found,
The team covers the corpse and make a corny joke about the nature of the death
They search for some suspects and bring in some people in an interrogation room
They grill on the person until he/she admits knowing how the person died and who is the killer
They find the real culprit and arrest him/her and cue the next episode of the same exact shit happening again and again.

An excellent television show put out by CBS, that has just finished its fifth season. It follows the cases (and sometimes, personal lives) of a group of forensic scientists...whose jobs are actually just an amalgam of careers found in the real world. But it's still really good.
Bob: Oh. My. God. Did you see last night's episode of CSI?
Susie: I totally did! I thought Greg was going to cry! He's so emo sometimes.
Bob: Yeah, it was awesome.

CSI: Crime Scene Investigation, a pretty solid prime time drama series that has its ups and downs. In its fourth season right now, the show has spun off two TV shows, CSI: Miami which is in its second season and CSI: New York, coming out this fall, two PC games, and even a board game.
According to CBS, CSI: Crime Scene Investigation is the most watched drama. The statement is also backed by TV ratings.
