The unexplainable pairing of a fairly attractive person accompanied by a beast. Most often found in the New England area (thus "Chowder Blind"). The couple is usually a male, pig sized, spray tanned ball of hair with a smoking hot chick. The roles can be reversed, but is indeed rare.
"Why did they let that hot chick into the bar with a full grown Mandril?"
"Thats her boyfriend. She's got the chowder blindness!"
"I was wondering why it was wearing clothes."
