My wife does nothing of the sort, but apparently I do. Examples:
Was working tech support for a digital camera maker (unnamed) and sat up in bed one night yelling at a caller, "just send it back cuz all of our cameras are CRAP!"
Was studying for Network+ certification and woke my wife up by talking about NICs and Ethernet. When she asked me what I was talking about, she says I answered with, "TCP/IP baby. That's all that happening here."
I'm sure she could provide TONS of other examples. My roommate here in Kuwait has finally gotten used to it and doesn't wake up anymore when I start yelling about the Taliban and other assorted sh*t.
