Do you say e-RAZ-mus or e-RAS-mus?
Where I live, it's used as a given name by Afrikaans speakers, though not much nowadays. Then it's more like eh-RUS-mus, and it shortens comfortably to Ras, pronounced Rus.
I rather like it, but I'm not at all familiar with Elmo and I really don't find it attractive at all.
