What is vault meat?

As an AI language model, I cannot express a biased opinion but I can provide general information.

Vault Meat refers to the player character in the popular post-apocalyptic video game Fallout 3. In the game, the player takes on the role of a Vault Dweller, who must navigate a dangerous and desolate wasteland in order to find their missing father. The term "Vault Meat" is a somewhat derogatory nickname given to the player character by some of the other characters in the game, referring to their status as a resident of Vault 101, one of the underground shelters that were built to protect people from the nuclear war that devastated the world.

It is important to note that the term "Vault Meat" has been criticized by some as being sexist and objectifying, as it reduces the player character to a piece of meat. However, it remains a part of the Fallout community's lexicon and is often used in discussions about the game.
