More Buffy references:
-The Big Bad.
-Bully Benrubi: Abraham Benrubi played Olaf the Troll on a couple of Buffy episodes. He also played the bully on an old 90's TV show, Parker Lewis Can't Lose.
-Arson Wells is maybe Orson Welles?
-Bigger Dan Ewe, obviously, is Bigger Than You.
-Billie Krystal is Billy Crystal.
-Black Hat Bailey is a reference to old-school westerns, where the villain always wore a black hat.
-I can't see the name C.H. Threepwood without thinking of Guybrush Threepwood.

-Davis Wayne Newton: Wayne Newton is an American musician.
-Dean "Deano Machino" Daniels: "Deano Machino" is one of the nicknames Chris Jericho called Dean Malenko during their famous feud.
-Dermot O'Logical: probably obvious, but a dermatology reference. Note the misspelling; wrestlers aren't known for their grammar.
-Duke Hazzard: The Dukes of Hazzard.
-Someone mentioned Clinton Washington. Well, there's also Grant Truman.
-Ed Monton: Edmonton, Canada.
-Eva Berlin: Hitler's wife, Eva Braun.

-Little Bill Lewbowski: The Big Lebowski?
-Marshall Dillon was a character on Gunsmoke.
-Mercutio Sleep: One of Mercutio's most famous monologues in Romeo and Juliet is about sleep and dreams. Though on rereading, it has a lot more to do with dreams than sleep, so a bit of a stretch.
-Nelson Callum: Nelson's Column.
-Nevada Nuclear: It's pretty well known that the U.S. has done a lot of nuclear weapons tests in the Nevada desert.
-Notorious F.R.E.A.K.: Notorious B.I.G.?
-Pablo Rodriguez: This one is a major stretch, but in The Good, the Bad, and the Ugly, the priest who took them in when Clint Eastwood's character was dying of dehydration was Pablo Ramirez.
-Roger the Dodger was American football player Roger Staubach's nickname, but it's also apparently a UK comic strip character, which seems the more likely reference.
-Sam Sparrow: Australian singer Sam Sparro?
-Whiskey Jack is a common anglicized form of Wisakedjak, an Algonquin spirit. He showed up, among other places, in Neil Gaiman's award-winning novel, American Gods.
Some finishers:
-Vendetta's Anarchy in the USA move is a reference to the song Anarchy in the U.K.
-Jessica Bunny's Bunny Boiler finisher is a Fatal Attraction reference.
-Catherine Quine's Cat's Cradle is a Kurt Vonnegut reference.
-Ashley Grover's Chicago Hope might be named after the TV show.
-Art Reed's Dark Matter might be named after the Porcupine Tree song.
-Delirium's Dazed and Confused is probably named after the movie.
-Slayyer's Dead Zone is probably from the Steven King novel.
-Sean McFly's Delorean Driver is from Back to the Future. The main character is Marty McFly, and to travel in time, he drives a Delorean.
-Sergei Kalashnov's Eastern Block is a reference to the Eastern Bloc, a Cold War era name for the communist countries in eastern Europe.
-The Enygma Variation is a reference to the Enigma Variations, a piece of classical music.
-Sister Beth Mercy's Flying Nun is probably from the TV show.
-Notorious F.R.E.A.K.'s Freak Out could be named after the album by the Mothers of Invention, though it more likely comes from the slang term.
-Frehley's Comet: Haley's Comet.
-From Canada With Love: From Russia With Love.
Steven Parker's Future Shock comes from the book by Alvin Toffler.
-Gentleman Jim King's King Maker is a reference to England's War of the Roses.
-Owen Love's Love Gun is from the KISS album.
-MDK is referenced by several moves. It's short for Murder Death Kill, a phrase from the movie Demolition Man.
-Pandemonium is the capital city in Hell in Milton's Paradise Lost. PandAmonium is Panda Mask's finisher.
-Whistler's Rebel Yell probably comes from the Billy Idol song. It probably doesn't come from the Civil War Confederate battle cry, seeing as how he's playing a Patriotic Face character in a northern promotion. Though it does give me an idea for a heel turn...
-Tommy Cornell's Rough Ride is hard to pin down. The most common mainstream association with the phrase is Theodore Roosevelt's Rough Riders, but as it turns out, there's also a British military regiment with the same nickname. Since the British unit took their name from the American one, I'm going to call it a TR reference.
-Flemmy Lemming's Suicide Solution was an Ozzy Osbourne song.
-Eric Future's Time Slice may be a Terry Pratchett reference. In his novel "The Thief of Time", his character Lu-Tze uses a time travelling technique called "Time Slice" to do otherwise impossible things.
-KC Glenn uses "Tune Up the Sunshine Band". Almost certainly a KC and the Sunshine Band reference.
I don't know if you're counting the other Cverse mods, but in Cverse 97, there's Outbacker Harris and Outbacker Rolf: Australian musician Rolf Harris.
