This term was coined in honor of the bright orange "shop" extension cord.
It applies
despite the true color of the extension cord in question.
We don't have the knowledge to do that, so we guess.
And the monk ended up with legs that would bow as he lifted his arm.
Which led us to make stronger legs for the
next attempt.
So, "haunt engineering" means, give it a guess, try it out,
and try to improve it next time.
