Octopus Stretch/Octopus Hold:
The wrestler stands behind the opponent and hooks a leg over the opponent's opposite leg. The wrestler then forces the opponent to one side, traps one of the opponent's arms with their own arm, and drapes their free leg over the neck of the opponent, forcing it downward. This elevates the wrestler and places all the weight of the wrestler on the opponent. The wrestler has one arm free, which can be used for balance. Below, AJ Lee uses this move in the WWE and calls it the Black Widow.
(AJ Lee using the Black Widow):
Since this move is all over the place in the major men's and women's pro wrestling leagues (as well as by other independent, non-league producers) if I come across any particular events that feature it often I'll post them for your reference. A very sexy move, if you ask me.
That's about all there is to say about that.
