逆エビ固め
This typically starts with the opponent on their back, and the wrestler standing and facing them. The wrestler hooks each of the opponent's legs in one of their arms and then turns the opponent face-down, stepping over them in the process. The final position has the wrestler in a semi-sitting position and facing away from the opponent, with the opponent's back and legs bent back toward their face. Chris Jericho uses this move in a high angle version, calling it the "Walls of Jericho". Lance Storm also performs this move with both versions, including the regular Boston crab and single-leg Boston crab. He usually sets it up from a single-leg takedown or a roll-through called the "Calgary Crab". Samoa Joe also uses an inverted powerbomb as a setup into the Boston crab. Charlotte Flair uses this move to set up for the "Figure Eight Leglock"
