I was reading about the poisonous beginnings of raw cashews and found a very insightful and helpful quote in the comments:
"As mentioned above, cashews are part of the poison ivy family and I think the raw cashews I bought were poorly steamed because my anus (butt hole) is really really itchy especially right after I go to the bathroom."
Anus has been one of those words that I just never really knew what it meant, so I have just sort of nodded along all these years when I hear it in conversation, but after reading this person's comment, so much has been explained.
Thank you, Intarwebz.
