Thatha is a word of Indian-origin having the definition of "old-man or grandpa." Now it can be used to joke around with friends. Calling someone a "thatha" means they are turning into an old person. This can be because they are losing their hearing, having back pain, or forgetting their memories.
Bruh, how could you forget my birthday? You're such a thatha!
