A really old person who has no idea what a phone is and constantly tells you about 'back in their day' which was WAY back before
even your grandparents were born.they can often be rude and people use 'old fart' as an
insult to a
non modern,or lame person.
Bob: let me tell you about how it was back in my day,when we didn't have phones or medicine or
anything
Becky:No you old fart I don't wanna hear it
