On the Greatest Generation podcast, they say RSVP instead of RIP among other little in jokes.
If you haven't listened to it, it's a pretty funny take on basically every episode of Trek at this point. It starts a bit rough (and slightly inappropriate with some Wesley jokes IMO) but it gets good quick and now it's a fulltime job for the hosts. It's a good time if you're looking for a parasocial relationship with a couple of Trekkies.
