Have you and your significant other/family/friends invented words?

Are there any words you’ve invented with those close to you, that “outsiders” just wouldn’t understand?

Here’s an example of a word that my fiance and I have invented:
Marple (v., zool.): to meow at one’s owner with the intent of waking up said owner so that (s)he can feed you/pet you

I’ll add more as I think of them.

I’m just curious to know what you all have to contribute; it’s a fun little thing between the two of us, but maybe we’re the only silly ones out there :)
