face someone down—confront smb. in an attempt to subdue or dominate the person:
- The project is too important to be placed in jeopardy by the vanity of one man, and those who are too cowardly to face him down.
face up to someone—challenge a person boldly; refuse to be intimidated:
- Confrontation may not be your desired choice but unless you face up to a person or situation your views will never be heard.
