Verb. After accepting an invitation or agreeing to go out you cancel at the very last minute using a lame excuse like "I have to work late", "Not feeling good all of a sudden", or "I got a sudden case of diarrhea ambush".
I sent in my invitation to Eric and Amanda's wedding but don't feel like driving 8 hours. I'm going to radack it and say I have to work over the weekend.
