Sin biscuits are when a cat makes biscuits (kneads) in an attempt to reproduce or rub one out. This is done with either another animal or an inanimate object like a stuffed toy.
Susan: Look how cute my cat is! He's kneading that toy so intensely!
Mark: Hate to break it to you, Susan, but them's sin biscuits.
