I don't know, but I suspect he chose the name based on the word LUDICROUS.
...Then again, maybe he meant his name to be LUDICROUS but couldn't spell it (pronunciation has nothing to do with this type of "artist").
.......But you never know; Maybe his parent(s) were just weird.

Perhaps his mother just never got over "Brad" and wanted her revenge. ;)
