its really infuriating to deal with or see but it not to the point of anger so you live with the constant burden of knowing there is an imperfection somewhere around the world that you saw and can never fix.
"hey want to see something mildly infuriating", "yeah" "look at the base... it doesn't move but the blades are wobbling. it will stay like that forever."
Something that doesn't quite get on your nerves or piss you off, yet. Also, the key word is potentially, so chances are it can really piss you off sooner or later. Think of something you found cute or hilarious for about five minutes, like a semi-witty dick joke, or an incontinent puppy, will later be potentially infuriating by repitition. Reference puppy dog girlfriend for a better irl example.
Person a: Does that chick relize that being a puppy dog girlfriend doesn't make her cute at all anymore?
Person b: He doesn't care whether or not that's potentially infuriating, he just gets pent up about it and fucks the shit out of her later
Person c(puppy dog girlfriend's bf, appeared from behind):
damn skippy, what she on't know won't kill her
