A sexual technique in which two men, one lying on his stomach and one lying on his back, face opposite directions, as earthworms do when they mate. They then sodomize each other at the same time, being careful not to squish each other's testicles. Named after Littleton because it was the preferred sexual position of Columbine killers Eric Harris and Dylan Klebold.
My legs are sore as hell today. Me and Todd gave each other the Littleton Earthworm last night!
