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