Gettingthe itis (tired after eating immense amounts of food) while being crazy drunk and high.
"Dude that party was crazy! I took too many shots, smoked a fat L, and ate a bucket of kentucky fried, I passed out like right away."
"Damn man, sounds like the crunkitis hit you hard."
A state of mind that is much crazier, drunker and sloppier than the already widely used crunk. Based on famous newscaster Walter Cronkite, if you have had so much to drink or smoke that you have achieved the level of Walter Crunkite, you should probably slow down.
