le désir brûlant translated to English means "The Burning Desire". The burning desire is like a fire inside of you, driving you full force to do something. It's either get there or die trying.
"I have le désir brûlant to make a change in this world. I will make a change, no matter what it takes.
A gamer superstition. The Desire Sensor detects what rare item, or event you are farming for, and prevents the game from giving it to you. Only when you forget about it, or no longer need it will the item drop, or event happen.
"Holy shit the Godsword Dropped! I remember running this dungeon for months, and I never got this damn thing. Of course now its worthless. Friggin Desire Sensor, why do you tease me so."
-MMO player's lament
Sudden severe confusion that occurs in one's brain when someone has to shit very badly and access to a bathroom feels unattainable. Someone with shit delirium may do unexplainable things.
George had to shit like there was no tomorrow. He was up to his eyeballs in shit. He displayed shit delirium when he inexplicably tried to unlock an unrelated lock that went nowhere when the bathroom was only a few steps away.
