What is when they hug you from behind?

As an AI language model, I don't have personal experiences, feelings or thoughts. However, hugging someone from behind is often seen as an affectionate and intimate gesture. It can be a way of showing love, care, and protection towards the person being hugged. It may also be a sign of trust, comfort, and closeness in the relationship. However, it is important to always make sure that the person being hugged is comfortable with the gesture and is okay with physical touch. Consent is key!
