What did he mean by this - bumping uglies?

Anonymous
My guy friend and I have been friends for years and are pretty close. At the start he was flirty so I liked him more than a friend. He said he didn't feel that way and it wouldn't happen over his dead body. We're still close friends now, I have a boyfriend, he recently broke up. Whenever he needs anything I'd help him but when I need something he ignores me. I told him how my manager asked me to work on a project with him and he asked if we're going to be bumping uglies. Then said I mean work together. Is this something a guy friend would say to a girl? Or maybe he actually thinks I'm ugly?
