Shameless, outrageous, or undisguised; also used to describe animals with a white or bald-looking face marking.
From 'bald' plus 'faced,' originally describing someone so bold they showed their face openly without a mask (in a time when people hid behind masks or deception), evolving to mean brazenly obvious.
A 'bald-faced lie' is one told so obviously you don't even care if people know it's a lie—it's fascinating how a physical description (a white-faced animal) became metaphorical for shameless behavior!
