You mean the movement that's implied in the jump? I'd say its either something like a kata guruma ("shoulder wheel", it's a judo throw where you lift the target in a fireman's carry-ish hold and dump him/her to the other side), or a leg lift with high kuzushi using the other hand. Don't know if that takedown has any formal name, but the Argentine SKIF website lists the double handed move as morote koko gamae
every time someone reposts that article about the 3/4 rotation punch, choki motobu kills a makiwara.
please, think of the makiwaras.
