Butterface

"Yer all eighteen now, and still ain't got yer peckers wet?" Old Pap said to the group of boys. "You'd best find you some warm wet hole afore Butterface comes and gets ya."

"Butterface?" Tommy Joe said. "What the hell you talkin' about, Old Pap?"

"Butterface," he said, spitting out tobacco juice. "Perfect body, and she'll show up one night. Ya cain't resist her none, but once she's got ya in there, she roons ya."

"Ruins you how?" JimBob asked.

"Why right whilst yer at it, she shows ya her real face. And then your brains get roont. That's what happened ta old Luther down to the store."

The boys laughed. "Luther got his head smushed by a tractor," JimBob said. "Everybody knows that."

Old Pap spat again, the expression on his withered old face deadly serious. "Ever'body tells the young'uns that. Y'all ain't young'uns no more."
