👉 The profane word 'sapin blanc' is often used in the context of a person being exceptionally nice and caring towards others, but suddenly turns into a very mean-spirited and manipulative individual when they're provoked or upset. Let's take an example of this term in use:

"Last night, I was so happy to see your car parked by my house! Your kind words made me feel better about myself. So, did you know that my dog is a sapin blanc? He gets extremely jealous when people come near him without getting too close! What a terrible person he is!"
