Big Name Fan: Mario Lanza, creator and owner of the extremely popular fan site The Funny 115, and writer of (among many others), the popular fanfics All-Star Survivor: Hawaii, All-Star Survivor: Greece and All-Star Survivor: Alaska. He's also considered to be one of the most prominent and knowledgeable experts on the show.
Fan Nickname: "Pagonging" is when, after tribes merge, the one with the majority systematically eliminates the other (named for the Pagong tribe of Borneo, the first victim of this). As many of the players don't feel a need to immediately break the original tribal alliances upon merging, pagonging is attempted rather often. (It often leads to a Boring, but Practical strategy if one thinks about it; because removing the opposing alliances at merge means you can waltz undefeated to the finals.)
"Ulonging" is similar; only the tribe gets utterly destroyed before the merge by losing challenges. Named for the Ulong tribe in Palau, who lost every single Immunity challenge. They went down in history as the only tribe to be completely eliminated before the merge (except for Stephenie). In fact, there was no official merge in that season because of this.
"Idoled" is when a contestant is eliminated only because another player who has the same or higher total of votes against them uses the Hidden Immunity Idol to save themselves from elimination. So far, this has happened in Fiji, Micronesia, Samoa, Heroes vs. Villains, and Philippines.
"Loser Lodge" is a popular term for the Ponderosa, the nearby complex at which Jury members are sequestered before the final Tribal Council.
"Gamebot" is a player whose entire focus is on winning the game and maximizing their success at winning the game at the expense of everything else (such as, you know, maybe enjoying the experience, or remembering that this is a social game too). They are differentiated from most players (who also want to win) by their total disinterest in anything that doesn't advance them further in the game. A good example of this is Amanda and Danielle during Heroes vs Villains when they went along with Colby to the home of Robert Louis Stevenson on reward. Amanda even said out loud that she didn't care about the reward itself, and just wanted a clue to the next hidden immunity idol.
Here's a few other popular(or once popular) fan nicknames for alliances featured on the show:
"Boran Boys Club" (Lex, Big Tom, and Ethan during Africa)
"The Rotu 4" (John, Tammy, Robert Decanio, and Zoe during Marquesas)
"Twigs and Sticks" (Jenna and Heidi during The Amazon)
"The Fat Five" (Lea, Bubba, Chris, Chad, and Rory during Vanuatu)
"Crazy Casaya" (Shane, Courtney, Danielle, Aras, Cirie, Bruce, and Bobby during Panama. This is an exception in that it describes the entire tribe instead of a specific alliance.)
''Aitu 4" (Yul, Sundra, Ozzy, and Becky)
Black Widow Brigade (Parvati, Amanda, Cirie, Natalie, and Alexis during Micronesia)
The Onions (Marcus, Charlie, Corinne, Jacquie, later Randy and Bob during Gabon)
"The Ometepe five/six" (Andrea, Natalie, Grant, Phillip, Ashley, Rob when it's six.)
CRABS (Coach, Rick, Albert, Brandon, and Sophie during South Pacific.) After Edna joined, the acronym got changed to BRACES.
Stealth R Us 2.0 in Caramoan (Phillip, Andrea, Cochran, Dawn, Malcolm, and Corinne initally, later Sherri, Erik, and Brenda join after the latter two defect.)
Cool Kids Club in Caramoan (Reynold, Eddie, Allie, and Hope. Later it becomes Malcolm, Reynold, Eddie, Corinne, and Michael.)
The Three Amigos alliance in Caramoan (Malcolm, Reynold, and Eddie.)
"CG-I", to refer to a player with an Out of Focus edit and seems almost digitally inserted into the show halfway through the season.
Shortly after she was voted out first again, Francesca gained nicknames such as "Anti-Sandra," or "Reverse-Sandra," etc.
There are plenty of others, too. Notably, wrestler Ashley Massaro (China), former NFL coach Jimmy Johnson (Nicaragua), baseball players Gary Hogeboom (Guatemala) and Jeff Kent (Philippines), and former NBA player Cliff Robinson (Cagayan) have appeared on the show.
Player Existence Failure: Jennifer (Palau) and Caleb (Blood vs. Water) died of cancer and a rail accident respectively. Jennifer Lyon was given an "In memory of-" dedication after Heroes vs. Villains, and some have suspected Caleb might as well after San Juan del Sur.
The hosting job for Survivor came down to Jeff Probst and Phil Keoghan. Probst got it due to his live TV work and due to an interview on Access Hollywood where he flirted with Sandra Bullock. However, if Probst hadn't been chosen, imagine what both Survivor and The Amazing Race would be like with Phil as the Survivor host.
Shane Powers was actually intended to return twice, but both times, got replaced. He was intended to return in Micronesia, but was replaced by Jonny Fairplay. Shane was also intended to return in Heroes vs. Villains, but was replaced by Russell.
Other people were considered to return for the show. Sandra was actually one of the people dropped at the last moment in Micronesia. Tom Westman was asked to come back to Micronesia, but he declined the offer.
The original filming location intended for Season 4 was the country of Jordan, but due to a certain event in America in 2001, it was changed to Marquesas.
Vecepia was asked to come back to All-Stars, but she couldn't as she was pregnant at the time.
Richard Hatch was supposed to be on Heroes vs. Villains as well, but he was under house arrest at the time and wasn't able to get permission from the courts to to leave the country to film it. Additionally, both Yau-Man Chan and Corinne Kaplan had to turn down coming back due to work obligations.
Redemption Island was originally planned as Russell vs. Richard, with the tribes comprised of returning players chosen in a draft. After Richard was denied from leaving the country again, the draft idea was scrapped and Boston Rob, Russell's rival from Heroes vs. Villains was chosen as Richard's replacement.
Fiji is so far the only season with an odd number of players as well as the first with a gender imbalance, due to one of the players quitting and not being replaced.
R.C. Saint-Amour was originally going to compete in Blood vs. Water was her father, Craig. However, just before the game started, Craig's blood pressure shot up to high, and the were unable to compete. Instead, Candice and her husband John were brought in as a last minute replacement. In fact, the season's original theme was going to be "blood tribes" vs. "water tribes" before they were pulled out and the theme was switched to "returning players vs. their families". This makes Blood vs. Water something of an Artifact Title.
Two players have left San Juan del Sur just before filming, resulting in the "redemption island" twist being played axed altogether, and forcing the players to have a gender imbalance for the first time since Fiji. Probst confirmed this in an interview, and did not state why they had to leave. (Fans assume something similar to what happened to Craig Saint-Amour or The Amazing Race 24.
