What does it mean when a guy says "you're cool" ?

Anonymous
I've been talking to this guy for a couple days and we've talked all day and he told me he just wants to be friends with benefits and he got the app because he was bored and lonely now I don't know if that's what friends with benefits do or not but something tells me there's more. He also tells me I'm cool.. What does that mean? No smart answers please.
