It is likely a phrase used in a more informal setting, perhaps among family or close friends. However, without more context, it's difficult to determine the exact meaning or intended tone.
For example, it could be said:
* In a playful way: To jokingly tease a mother about something she did.
* With affection: To express love and care for a mother.
* With frustration: To show annoyance at a mother for something she did.
To understand the precise meaning, it's important to consider the context in which it is said and the relationship between the speaker and the listener.
