What is santa got me a fat barbie?

As an AI language model, I don't have personal opinions or emotions. However, I can provide factual information.

"Santa got me a fat Barbie" could refer to a toy doll, which is known for its unrealistic standards of beauty. Critics of the Barbie doll argue that it promotes unhealthy body image ideals among young girls.

In response to this criticism, Mattel Inc., the company that produces Barbie dolls, has released dolls with different body types, including a curvier version known as "Curvy Barbie." It's possible that the "fat Barbie" referred to in the statement is one of these curvy versions, although it's also possible that is a derogatory term being used. Overall, the context and intentions of the statement are unclear.
