During the 2016 PokerStars Caribbean Adventure Single-Day $50,000 High Roller, I overheard Steve O’Dwyer (who went on to top the 80-entry field to win his fifth major European Poker Tour title and $945,495) talking to Scott Seiver about an "Oreo Cookie Tell,". Intrigued, I had to find out more.
I’m sure the term has been bandied about for a while, but this was the first time I’d heard it and I absolutely loved it. For me it was an instant classic on par with Phil Laak’s coinage “felted” for losing one’s stack (rumor has it he’s the one who first employed that term).
