I would say SEH-bree-uhn, but I would be wrong. LOL. It makes me think of the brain (I guess because of the -brian but also its similarity to the word "cerebral"). I don't think it necessarily "goes" with
Arsenio or
Ocean at all.
Arsenio (being in the U.S.) only makes me think of
Arsenio Hall. I guess it sounds fine with
Boaz and
Thor, but especially nice with
Dante.
