Do You Use Any Code Words? Please Share! [SURVEY]

I shared this morning that when our kids were little, Sheri and I used the code word "HoHo" instead of Santa to keep secrets from our kids. Our Internet guy Andrew shared that his high school friend group used the code word, "House Plants" to signal someone should change the subject in conversation. What are your code words?

Do you have a code word for Santa? For sex? Maybe to signal that a topic is about to cause a fight in public or in front of the kids and should be discussed in private?
