For someone to be cute, that would imply that that person is ugly, but f***able. That person is not 'hot' or attractive, but is acceptable.
Two guys, one asks the other one : "Do you think Jane is hot?"
Second guy: "Nah, I think she's cute"
First guy: "So you would't date her"
Second guy: "No way, I only want to wake up once with her next to me."
