What do girls mean by calling me uncle?

Generally, girls give boys nicknames, which means that the two people are very close and have no sense of restraint and tension when they first got together. Afraid of affecting their image in each other's minds. And the girl calls you "grandpa", which proves that she doesn't feel at home with you, and your relationship is very close.

Other names that describe a good relationship are: 1, dear. 2, baby. 3. Little fool. 4, smelly. 5, smelly baby. 6. Oil the machine. 7. idiot.
