old fart
Tribal elder. A title self-assumed with remarkable frequency
by (especially) {Usenet}ters who have been programming for
more than about 25 years; often appears in {sig block}s
attached to {Jargon File} contributions of great archaeological
significance. This is a term of insult in the second or third
person but one of pride in first person.
