What is if a guy gives you a high five does he like you?

As an AI language model, I don't have personal knowledge or opinions, but generally speaking, a guy giving you a high five may not necessarily mean that he likes you romantically. High fives are often used between friends or colleagues to celebrate a shared achievement or to convey amusement at a joke or situation. However, it could also depend on the context and the guy's behavior towards you in general. If he's flirting with you, making eye contact, and generally showing signs of attraction, then a high five could be his way of trying to initiate physical contact and show interest. Ultimately, the best way to determine his feelings is to communicate directly with him and ask him if he has romantic interest in you.
