look up any word, like cunt:
 
1.
The itchy ass you get after eating a moderate to large amount of Cashew nuts. The itching may be the next day, or the itch may lie dormant for several days, and then strike with enough ferocity to cause you to shove a chimney sweep up your ass.
"Why is Dan dragging his ass on the carpet?"

"Eh, I think he has a case of Cashew Itch, from the looks of it."
