Having stumbled upon this thread in the TiTS board, I thought it would be fun to do one for Corruption of Champions 2. There are undoubtedly lots of references I've forgotten to mention or missed entirely, but here's a start at them.
Characters:
Aileh: Helia spelled backwards, referring to the CoC1 character.
Ambra: Derived from 'amber', which also happens to be what Kohaku means in Japanese. But that's a coincidence, nya-jya.
Alraune: The German word for 'mandrake' and the title and titular character of a novel by Hanns Heinz Ewers, which evolved from there into 'humanoid plant monster'.
Behemoth: Hebrew, a great beast mentioned in the Book of Job with a 'tail' like a cedar.
Benny: The cave troll who can go on a rampage through the Kervus warcamp is a reference to the comedic antics of Benny Hill.
Darius: A name of Persian origin, particularly associated with kings of the Achaemenid Empire.
Decima: A Roman goddess and one of the Parcae/Fates.
Doireann: A name derived from the Irish word for a grove of trees.
Fenraus: Derived from Fenoxo, who wrote a scene for the character.
Feronia: A Roman goddess of fertility.
Grainne: Named for a character from Irish mythology and possibly an old agricultural goddess; the name by itself means 'grain'.
Hashat: Named for a character from the Codex Alera series, see below.
Isadora: A Greek name meaning 'Gift of (the goddess) Isis'.
Kitsune names: Tobs has provided most of the meanings for the names on the wiki pages, all of them being Japanese names. So here's a link to the list of floof characters rather than having to retype all that stuff out.
Liulfr: A name derived from Old Norse, meaning 'wolf'.
Lucia: A Latin name derived from lux, a word for light.
Lumia: This isn't direct or confirmed but I'm guessing that Sun Mommy's name derives from another Latin word for light, lumen (pl. lumina).
Nocturna: The feminine form of the Latin word meaning 'of the night'.
Noire: The feminine form of the French word for the color black.
Nona: Another Roman goddess and member of the Fates.
Orlaith: A name derived from Irish words meaning 'Golden Princess'.
Salwah Amin: Per Tobs, from two Arabic words meaning 'comfort' and 'the truthful'.
Sigrune: Sigrún is a valkyrie in Norse mythology, the name means 'victory rune'.
Solveig: A name of Old Norse origins (the etymology seems disputed) and the heroine of the play Peer Gynt.
Tamarind: A tree (and the fruit it bears) widely cultivated in tropical areas.
Vacia: Not direct or confirmed but I suspect it's derived from vacca, the Latin word for a female cow. In Ladin, it actually is a word with that exact origin and Vacia used to be a cowgirl so...
Valencia: A Spanish name evolved from the Latin valentia, meaning 'valor'.
Vitruvius: A Roman architect and engineer whose writings on the proportion of the human body inspired Leonardo da Vinci's Vitruvian Man.
Books, Movies etc.:
Castlevania: In Silly Mode, the Champ (in 'Champion' personality) will use the 'You don't belong in this world!' line from Symphony of the Night.
Codex Alera: Hashat's name and partially her appearance are taken from a character from this series, a female Marat of the Horse Tribe.
Discworld: Undoubtedly there are references I'm forgetting but the one that immediately sticks out is the letter you find on the Mage Ship that prompts Gweyr to comment that five exclamation marks are a sure sign of an insane mind. It's taken from the book Maskerade. Also, Tobs has mentioned that (CoM spoilers) the way the Seven are defined by what people believed about their gods at the point of their awakening is similar to how Discworld works.
Dune: Salwah's comment that 'the spice must flow' when asking about Spice (when Cait isn't present) comes from the 1984 film adaptation of the book.
Dungeons and Dragons: Per Tobs, the Avanai are a a lawyer-friendly take on the Aarakocra.
Fist of the North Star: Lumia's 'Cum' sex scene in Silly Mode includes a play on Kenshiro's iconic 'You are already dead' line.
Frozen: There's a Silly Mode-only reference to the film on one of Ryn's date scenes when she begins to ask the Champ if they want to build a snowman (and Ryn herself has a few similarities to Elsa).
Ghostbusters: Arona's quest 'I Ain't Afraid of No Ghost' references the recurring line in the movie's theme song.
Ghosts and Goblins: The dream sequence with Ogrish where the Champ complains about their armor exploding after a single blow comes from the gameplay mechanic in this series that leaves its hero in his underwear after taking a hit.
JoJo's Bizarre Adventure: Lusamine's second and third Flirt scenes in Silly Mode are modified to reflect a scene from near the end of the third arc of the story, Stardust Crusaders.
Legend of Zelda: The randomly spawning treasure room in BerryQuest and the value of the item you find in it are a reference to the hidden 'Chris Houlihan Room' in A Link to the Past.
Monopoly: There's a Silly Mode reference to passing Go and collecting money in Lumia's 'Slow Grind' sex option.
Monty Python: In Silly Mode, the Ley Crystal Grenade's item description contains a reference to the Holy Hand Grenade from the film Monty Python and the Holy Grail.
Star Wars: Brother Sanders is explicitly based on Obi-Wan Kenobi and the Higher Ground quest is packed with references to the films, starting with the name. In the quest Attitude Adjustment, the Frost Hound scene in Silly Mode opens with a reference to the cantina scene in A New Hope.
Music:
Smash Mouth: A play on the lyrics to the song 'All Star' appears in Silly Mode in Lumia's 'Slow Grind' sex option.
Miscellaneous:
Atha's Canvas: The book in Matiha's bookshelf, named after the TiTS character Atha written by Adjatha.
Dye-ing To Get To Know You: Everything said about the dye in this quest is a reference to Tyrian purple.
Khushkan Horde: The name was inspired by the Kushk River, per Aly.
Nivas' Depths: The book in Matiha's bookshelf, Savin written backwards.
Oxonef's Bounty: The book in Matiha's bookshelf, Fenoxo written backwards.
Winter City: Aly's doc for Ryn's dates contain a lot of comments about where she drew inspiration from, with the cooking being taken from different Scandinavian foods, referencing a real hymn in another scene and so on.
