Brother-in-law's fortune-telling _ Master's brother-in-law

? Today, I went to the hospital to visit my sick cousin, but my second aunt took us to the inpatient department from the hospital gate. Because of the epidemic, we couldn't enter the ward, so we had to chat with my second aunt downstairs. During this period, my second uncle always called me "Big Brother-in-law", and I was always puzzled. My cousin and I are both girls, and we don't have much contact with our husband. Of the four people at the party, only my husband is a man. Can you call me husband? Later, he mentioned that my car had a little accident during the summer vacation. With the name "Dajiefu", I am clearly calling me Mr. ..

? Everyone knows what "brother-in-law" means, but we really haven't heard the name "brother-in-law" for a long time. My second aunt and father shouldn't call me husband like that. The simple old people in our hometown like to call their juniors as a sign of respect. I haven't heard it for a long time, but I'm not used to it at first sight. This stalk is enough for me to laugh for many days.
