The Fuzzy Pumper Barber Shop. WTF happened to jingles? This one was dead and buried in my head until just now.
Edit: see the sibling comment, they gave a link. Brother need a little off the top.... and I never even had this or most of the crap whose jingles are still in my head.
I assume it means https://en.wikipedia.org/wiki/Fuzzing which in this context would be trying the idea with multiple input parameters until one works best. Kind of like neural networks.
