Ahhh, she meant to say gore. Yes, you are right, that means qabar. The only thing related to gore and khunaa that I can think of is “khunaa” = khodna. Again, it may be a different word and MKD spelled it differently. I don’t think a mother would say this to her son “tumhari qabar khodoon”. I think you guessed the gaur part right. If MKD comes back with the sentence, we can then help her more. Good job discovering the actual word though :k:
…tabaydar…
