From P2SR Wiki
Overview
Partner Cube Glitch (also known as Cube Glitch, Cube Cheat or Super Jump) is a physic engine glitch in multiplayer which allows your partner to accumulate vertical velocity and it also triggers Player Physics Deformation. It is not useful in Challenge Mode, nor in AMC due to the slow setup needed, however the majority of the cooperative least portal maps require it.
