The other fun one is people who refer to the input files for the simulation packages as &quot;input decks&quot; (aka, punched card decks).  I occasionally get a funny look when talking to someone from outside the computational science community use that term.  And I&#x27;m in my 30s - punched cards were history by the time I started using computers myself, so this kind of terminology isn&#x27;t really generational - it seems to come from specific communities.
