Da horridly-acrid-mooded "horned monster" dat Linus's short-fused big sister becomes whenever anything doesn't go her way.
A classic "Lucyfer" moment:

Linus: I hate to mention it, but you've been awfully crabby since Christmas.
Lucy (scowling): Anybody who is at all sensitive is bound to have a post-Christmas letdown!

Lucy (outburstingly squalling at the top of her lungs, so that her mouth appears as a huge round black cavern): NOT AT ALL!!!
Linus (does his familiar "flip-flip" somersaulting over backwards in startled shock)
