Where did I pick that up?

For awhile now, the phrase "amaze-balls" has been in my head. As in, "that chocolate cake looks amaze-balls." I'm not sure where I picked it up. Or why. Did someone else say it? Did I read it somewhere? Am I acquainted with someone who said/says it and only my subconscious picked it up? It is a mystery. I try not to use it in conversation or in response to something on social media. People might not get it or might be offended. But I am curious as to why it's been going through my mind lately. And where I got it from.
