Yay for idiots!

Jon here.

Okay...so I'm play testing a new deck idea last night, chaos sphere cyclone...and I go up against a kid using a Pyschic deck.

He's about to scoop when I have to tell him to use his Pyschic Borg to remove two monsters to pump it up to 2500.
He does so. And even uses Snail to attack over both my Armed Wing and Dark End.
But he also plays Brain Research Lab. That field spell that accumulates counters in place of paying life points for using Pyschic effects.
He gains two counters that turn.
I set Dandy. Going for Black Rose once he has 4 counters and burn him for 4000 damage using his own field spell.
Perfectly solid plan, Im still at 7100 and as far as I know he doesnt have Twin Sword Maurader or something ghey to screw me over.
He summons Commander, doesnt synchro, instead continues to use its effect whenever his monster battles my floaters, accumulating 5 counters in total on his field spell.
Which was an illegal move because that activates during the damage step and a field spell has no where near high enough spell speed. But it was fine, wouldnt have changed the outcome, as I was planning to Black Rose then summon Armed Wing to attack for game.

Now Im thinking, great, game is mine, he has one face down, but even if he stops my Black Rose, I can fall back on other strategies using tokens and whatever I draw from Pot of Avarice.
Debris Dragon normal summoned. Okay.
Dandylion summoned. Okay
Synchro! Black Rose Dragon! Nuke!

He chains spell of pain.
"When a card effect ACTIVATES (key word kids) that deals damage to your life points, inflict that same amount on your opponent instead."
Hm. I see where he was going with this, and I believe the field spell's adverse burn effect doesnt 'activate' when it leaves the field, it just kind of...happens.

None of the effects start a chain.

But this kid still chains Spell of Pain, trying to burn me for 5000 damage, which wouldnt have killed me, but would have killed him.
Just for argument's sake, even if he could have chained spell of pain to his field spell, the timing of the activation is when it LEAVES the field. When Black Rose resolves it destroys ALL cards. Therefore, the timing when the field spell activates, Spell of Pain is no longer on the field!
Yet he persists to argue that I am taking 5000 damage.
Little moron.
Every time I say something he cried, "Lies!" (>.<)
I explain every part of the chain, exactly what happens and the exact order of events.
Black Rose.
Boom.
No field at all.
Your field spell then burns you and at this point, no Spell of Pain. No!

Now...his best argument to counter the rules of this game was this:

"Hurr durr derpa Black Rose is like a meteor and herpa derp meteors destroy the FIELD before anything else! Hurradurrrrpa therefore I can use my spell card!"

He equated my BlackRose TRADING CARD to a meteor.
Physical meteor, not Meteor of destruction, the spell, actual space rock.
And not even meteorite, which is the actual rock as it connects with the earth, but meteor, the beam of visible light announcing the entrance of a meteoroid has entered the atmosphere.
Well, obviously, at this point I had no choice but to concede to this little prick. His intelligence and superb stragety completely overwhelmed me and I had to admit defeat.

Derp.
