Tilt - to play wild or recklessly.
Tilt is more than playing wild and recklessly... I would say that "tilt" is when we lose control completely. It happens after making a few or more bad decisions. When we keep losing hand after hand and when nothing is working... So we start making irrational moves due to that frustration and anger, going all ins on any game at any odds. I had some good recoveries after "tilting", but many more times I suffered more significant losses... So "tilting" is really bad, when we let our bad emotions take full control most of the time it ends up badly!
