Scorpion Deathlock
From Luchawiki
A cross-legged submission, putting pressure on the victim's back ala a cangrejo. In Mexico, the victim will often be tilted over on one side, while the attacker grabs the victim's free arm for an added armbar. Elsewhere, the victim's stomach is completely on the mat. The Texas Cloverleaf is a similar move than ties the opponent's legs around a different limb.
While the hold is associated with Riki Chohsu, Sting, and Bret Hart, it appears to have originated from Mexico. Probably with Blue Demon.
