flat out
At maximum speed
Flat out means at maximum effort or speed: We've been working flat out to meet the deadline, She was running flat out.
It also means directly or unequivocally: He flat out refused to help, I flat out told her the truth.
The first sense suggests pushing to the limit; the second emphasizes bluntness without qualification.
