Dexit is the nickname of the decision that Gamefreak (Developers of the Pokemon games) decided to do with the 2019 titles "Pokemon Sword" and "Pokemon Shield" where they decided that most of the already existing pokemon will not be able to make it into the games. This decision is controversial due to the fact that Gamefrak clarified that no future pokemon game will ever be able to house all pokemon species again, leaving the lackluster 3DS titles being the last games that have all (at the time) 807 pokemon coded in.
little Jimmy: Man, I can't wait to use my old Porygon in the new games

Brian: Jimmy, you can't do that anymore. Dexit happened, and that means most of the pokemon are gone

Referencing Brexit, Dexit is the fan given name to the decision of Game Developper Game Freaks to limit the number of existing Pokémon that will be able to be transferred from previous games to the Nintendo Switch titles Pokémon Sword and Shield. Only pokémon that are part of the Galar Pokédex will be allowed to be transferred and used in the games, with others not being coded in, but available to store and use in Pokémon Home. Future games are said to also follow this decision, with the list changing every time.
Person 1: Dexit means half the dex is gone !
Person 2: Dude, it's just one pair of games.
