jailhouse stomp
n.— «Henderson, who has spent most of his adult life behind bars, dropped the receiver and walked over to Song’s cell, where he knocked Song to the ground with a punch in the head and then finished him off with what’s known as a “jailhouse stomp,” said Crown prosecutor Laura MacRae. “He delivered at least 10 kicks to the head of Mr. Song,” MacRae told the court.» —“Two years for remand attack” by Cary Castagna Edmonton Sun (Alberta, Canada) Oct. 25, 2006.
