In our house, apparently, it's "nap."
This, by the way, is Julie's joke. Or at least that's where I heard it first. But, since it sounds pretentious to quote other people's punchlines, I'll just appropriate it. It's in our marriage contract anyway. "Paragraph 293: All insightful or humorous comments shall fall under joint proprietorship upon utterance and memorization, however faulty."
This is followed by "Paragraph 294: Any and all statements, however faultily remembered, may be dragged out in future arguments as proof of numbscullness."
However, as you may or may not remember, in our Bill of Marital Rights, "Amendment 2: Arguments spice up a dull evening, but might cause long-term damage. So, if you happen to be the male party of the undersigned, think twice and then shut up anyway."
