The most beautiful word in the English Language - Lmud

LMUD - It must be a popular word. If you enter 5683 on a Nokia phone it appears when entering an SMS. I often enter that combination wanting a different word, but LMUD is what appears. Not only is this not the word I want, but I have no idea what it actually means.

If you cannot work out what word I want, enter it on your Nokia and see what other options come up. I am using a Nokia 6600 BTW.
