ELI5: Explain Like I'm 5

I Love You, Man

"I love you, man" is a way of saying that you really care about someone and want them to know how much they mean to you. It's like giving them a big hug or saying thank you for being a good friend. Just like how you might love your favorite toy or candy, you can also love people, and telling them is a nice way to make them feel happy.
