Embrace The Word

The word for today
is braggadocio, a word that looks
and acts and sounds like its meaning,
a truly bellicose noun with absolutely
no feeling for its fellow words.

Yesterday's word was
defalcation and contrary
to what I first thought does not
imply something nasty.

So what's the meaning of this?

A successful defalcator
should not, indeed, could not,
be a braggadocio.
