GA is a quick way to give a person permission to do something. For example, if you message your boss to ask if you can buy a stock at a specific price point, they might respond with, "GA, buy at 50 points."

You will most likely see people use GA when texting or messaging online. Character space may be limited, or they are in a hurry and want you to do whatever was proposed.
