1. Doctrine, theory, or the like. An assertion that something said, believed, alleged, etc., is false: Despite Dave's denials to the contrary, I just knew Kimball was merely hiding in a closet somewhere in our house and hadn't actually gone home to California after all. Hence my forcefully opening every door and yelling, "surprise!" Even now. More than 48 hours after his car drove away. I mean, that kid's gotta be getting hungry by now, right? Kimball? Oh, Kimball! You can come out now . . .
2. Refusal to recognize or acknowledge; a disowning or disavowal: I am in complete denial that our little California cowboy has returned to his own home so I continue to ask, "What does the cat say? What does the doggie say? What does the piggy say?" Dave usually gets it right on the very first try.
