"Dungeons and Dragons Free". Sometimes people on dating sites will write that they are looking for someone who is "D&D free." This is their way of indicating that geeks and nerds need not respond. Some people just aren't looking for such nonsense in a lover.
No, I don't want to roll a d20 saving throw to ensure that your Prophylactic of Exploding Love +3 doesn't break. I thought I indicated that I'm looking for someone that's D&D free.
When some resigns or retires from a job, they are on "eternity leave". This can also refer to someone who has passed away, especially someone who worked somewhere for a long time, retired/resigned, then passed away later.
Oh I'm sorry, you didn't know that Kelly is on eternity leave? She resigned and moved to Hawaii!
With regrets I would like to inform you that my boss is officially on eternity leave. I will never see or hear them again. Ever.
