"AKA" is an abbreviation that stands for "also known as." It introduces an alternative name, nickname, or description for the same person or thing. It is commonly used in informal writing, on social media, and in speech.
You can use it to introduce a person's official nickname or stage name, which is common with celebrities or authors. You can also use it to make a joke about someone's personality or behavior by giving them a humorous title.
For example:
Stefani Germanotta, aka Lady Gaga, is performing tonight.
My brother, aka the laziest person in the world, is still sleeping.
