Did I disrespect my uncle?

I was talking to my sister and I saw this blue fan in our living room and I told my sister I know this fan my uncle "amats" gave it to me and asked me back the fan my uncle heard it and he's pissed because I should be calling him uncle when he's girlfriend is here and I just only call him amats which means "addict" in our word if you reverse it you will get mata which is eyes and he's also peeping tom too. In reality he's peeing tom and addict. He said Im rude and he said not so nice things about me he said I shouldn't be calling him "amats" and he said if I ever get into an accident he won't be helping me because Im too evil I said he's the evil one because he's peeping tom and he said he wants to punch me. I guess Im sorry for my behavior too I just thought he's weird to react that way because of my comment on the blue fan. Am I rude here?
