Specific descriptions of how you taught your pet a button

Can anyone give specific descriptions of how they taught their pets certain buttons? I feel like I am really struggling to figure out how to teach some buttons, I understand how to teach simple ones like play, pet, or treat, but how do you teach more complex ones like “mom” or “ouch” or your pets own name? For example, if I were to press “bye” every time I leave, but then started pressing “mom bye”, would he ever learn that I am mom? Maybe I am overthinking things, but if anyone has any good explanations I would really appreciate it!
