Anyone who digs
in the ground or mines, specifically in search
of something buried. Can be more loosely used to include digging for other
reasons. Variations include forty-nining and forty-nined, et al.
Look, ma! That
dirty forty-niner just dug himself
up some pirates booty!
I was going
to go forty-nining at the beach today, but I read that
those areas have all been forty-nined already.
