The Walls Of Jericho (or, in WCW, the Lion Tamer) is Chris Jericho's submission finisher, its counterpart being the Lionsault.
It's close to the Boston Crab, except Jericho stands while doing it, putting pressure higher on the upper part of the back. In other words, Jericho flips the person over by the legs, so that their chest is flat on the mat, and wrapping his arms around their legs, he pulls back, bending the victim's back.
This also leaves Jericho's back open for a good chairshot.
