Yoko Wakare 横分
Side Separation
Mechanic
Uke leans their weight into tori, and tori vanishes: dropping flat onto their side with both legs stretched across in front of uke's feet, while their grip yanks uke's upper body forward and down. Uke's support disappears and they pitch headlong over tori's lying body.
Analogy
Someone plants both hands on a folding table and leans their whole weight onto it. The legs snap shut, the tabletop drops flat to the floor, and it's now a low ledge right in front of their feet. With nothing holding them up and their hands still going down with the table, they pitch straight over it.
Why it maps
The collapsing table is tori's sacrifice: the support uke leans on suddenly drops flat, becoming the very obstacle at their feet that their falling weight carries them over.
