Some terribly nerdy things that happened in our house in the last five minutes alone:
I said, "I need to find out more about the Prime Directive."
Steve said (aloud, in conversation), "REDACTED. My comment is redacted."
I said, regarding some drink glasses, "You are suffering from an unnecessary multiplication of entities."
And we had a conversation about Klingon penes. (Steve thinks they are probably barbed; I think that, when erect, they are probably VERY VERY hard.)
