Daring to the max: To dare someone to do something risky or challenging is one thing. Declaring the "double dog dare" heightens the challenge. The highest degree of challenge is to "triple dog dare" someone. It should not be used lightly, or frequently.
The most important DARE: [I] believe the most important dare is the D.A.R.E. (Drug Abuse Resistance Education) program.
