The expression "old enough to be somebody's father/mother" means that a person is significantly older than another person, to the extent that they could have been their parent. It is usually used to comment on an age difference between two people. For example, if a 30-year-old man is dating a 20-year-old woman, someone might say "He's old enough to be her father!" to express surprise at the age gap. It is important to note that this expression can be considered rude or offensive in some contexts, so it should be used with caution.
