A shrimp tie (海老責め ebi-zeme?) (also known as an ebi (海老?) or a kuri (繰り?)) is a type of Kinbaku bondage. It originated over 300 years ago in Japan as a torture and interrogation technique. Due to the forced bent down position of the upper body this position sends a burning sensation through the body if the subject remains in it for a long time.
Due to the knees which are widely spread the position resembles the legs of a crab or shrimp.
