Face Down Meaning

(transitive, idiomatic) To confront.

Example: Matthew Prior
  That old philosopher grew cross, / Who could not tell what motion was; / Because he walked against his will, / He faced men down, that he stood still.
2011 October 23, Tom Fordyce, “2011 Rugby World Cup final: New Zealand 8-7 France”[1], BBC Sport:
  An already febrile atmosphere within the ground before the start had been stoked still further when France's players formed an arrow formation to face down the haka, and then advanced slowly over halfway as the capacity crowd roared.
