Scrabble but ANY FAKE WORD wins on the spot???

It's Halloween, and Scrabble is now Spookbble, where playing phony words can win you games immediately. Wait, what!?
Playing fake words ("phonies") in Scrabble is allowed, but very risky, as you lose your turn if your opponent challenges. So it's always a big blow when your opponent calls you out on a phony. At least... normally.
But this is no normal position. Here, an expert missed an amazing opportunity: if he phonied, he could've pretty much won a game INSTANTLY after his opponent challenged it off! Wait, losing a turn would've been a GOOD THING? How??? You'll have to watch the video to find out!
