This guy's 'donk' comment was certainly uncalled for. With the preflop raising, he easily could have and should have put you on AA, AK, AQ, KK (albeit unlikley with his KK but it happens), QQ, or may be JJ. And he then figures he's way ahead with KK and that flop (QQK).

I've learned that there are some hands in poker where both players are just going to get all their money into the middle. Typically pre-flop with some combination of: AA v KK v QQ v AK. Happens all the time. And I've learned there are just hands you're gonna lose. Typically after the flop with: set v. set. (Negreanu busted at the 2008 WSOP Main Event w/66 floping a set of 6s vs. his opponent with 99 who also floped a set of 9s. After a re-raise Negreanu confidently says "Well, I'm not going anywhere". He did > the rail). Big hand vs. big hand. You're just gonna lose if you got the smaller of the two.

In your case, you couldn't possibly get away from QQQQ and he couldn't possibly get away from KKKQQ, morphing into KKKK. Big hand vs. big hand. He started ahead, but he's the one that actually got lucky on the river. I think in Doyle Brunson's first book Super System, he said if the only hand that can beat you is quads, you push it all in since quads are so rare. You're just gonna lose against quads, but since they're so rare, you'll win a lot more often with the best hand. The term donk is way over used.
