Is stabbing someone with an icicle really the perfect crime?
The coldness of his body through the bag jolts me like an icicle through my heart.
early 14c., isykle, from is "ice" + ikel "icicle," from Old English gicel "icicle, ice" (rel. to cylegicel "cold ice"), from Proto-Germanic *jekilaz (cf. Old Norse jaki "piece of ice," diminutive jökull "icicle, ice, glacier;" Old High German ihilla "icicle"), from PIE *yeg- "ice." Dialectal ickle "icicle" survived into 20c.
