Re: XKCD example doesn't work for me.
My preference is for private, family, invented words. As in what your kid called the fridge when he/she was 3 and couldn't pronounce fridge. (something like fwidjerer). Maybe a pair of words to be on the safe side. Just not obvious ones that every three year old seems to say. And any extra obfuscation you can add for length, and remember ( like a three because she was 3 when she said it).
