Points of evidence: 1) Earlier this evening, husband and I were having an argument about whether To Decimate means "to reduce to 1/10 of the initial number" or "to reduce by 1/10 of the total number". After duelling internet searches and a quick check of the OED, we came to an agreement that it means "to reduce severely", in general rather than mathematically specific terms. 2) husband has been trying to teach Tyrantina to speak Klingon. Just before bedtime tonight, he got her to say Qapla! (The Klingon battle cry). There's plenty more, but I'll stop there. So my question is, are we regular-geeky, or scary-geeky?
