Top Definition
The ecstatic, overjoyed state that an obese person enters when filling their face with food. The more calorific, the greater the height of delirium; for example a creamy chocolate pudding can induce extreme hysterical behaviour with a complete loss of their surroundings, hell-bent on ingesting as much food as possible.
"Shit, what's up with Fat Rich? He's bouncing off the walls with fudge cake all over his face!!"

"It's fat man delirium! Who the hell let him get at the cake?!"
