dig-up-the-corpse cute
Cute to a degree that would engender crimes against nature, inspired by the sordid tale of Laura Tennessen, whose corpse was dug up by Nicholas Grunke, his brother Alex Grunke and Dustin Radke of Madison, Wisconsin on September 2, 2006 after Nicholas Grunke saw a photo of Miss Tennessen accompanying her obituary.
"Yeah, she's cute 'n' all...but she ain't dig-up-the-corpse cute."
