In context I was picking my son up in the UK from primary school.
I park a few roads away because I know it's a residential area and many other parents block driveways the road over from school because they're the most important people in the world.
This road I park down has a 180° turn at the bottom with some double yellow lines going around the corner til just after the bend.
So I'm following this Audi estate, he's already attempted to pull into 2 spaces his car wouldn't fit, no signalling, no hazard lights to say sorry dude, nothing. All of a sudden he emergency brakes and pulls over on this bend on the double yellow lines. And apparently he's done because all lights go off and so does his engine. I am enraged by this point, being 5 minutes late I only had 5 more minutes to collect my son before he's sent to reception for collection. So I go past this fucking idiot and park about 7 feet away, off the double yellow and I proceed to run out the car. Audi idiot is smirking at me. Me! Mr I -Can't-Drive-Like-A-Civilised -Human is smirking at me as if to say, I know I'm a total twat, what are you going to do? 
Too many times do people get to park like absolute shit heads and get away with it. Well, not today...
"Fucking prick." I muttered, jogging past him.
"What did you say?" He seems utterly astonished.
I stopped dead in my tracks, turned to look at him and stated, "I called you a fucking prick."
And on I jogged.
Since then this guy has been getting his kid, his 10 or 11 year old kid to glare at me and they often exchange things and laugh when they know I'm looking.
I want to punch him, but what I want more is to know that I'm NTA, please reddit, I am at your mercy!
