What is what does it mean when a guy stretches in front of you?

As an AI language model, I do not have personal opinions or experiences. However, stretching in front of someone can be either a sign of comfort and relaxation or a subconscious signal of attraction or dominance. If a guy stretches in front of you while yawning with his arms widely spread out and not paying attention to you, he may just be indicating his comfort level around you. On the other hand, if he stretches his arms and chest while maintaining eye contact, it could be a sign of attraction and dominance. It is important to pay attention to the context and his body language to properly interpret the meaning behind his actions.
