Well, as we know, uke in toribash is the blue guy.
But, in real life, Uke was a living aikido crash test dummy.
P.S. Ukes real name is ukemi
Briefing of an aikido move:
The version of the "four-direction throw" (shihōnage) with standing attacker and seated defender (hanmi-handachi). The receiver of the throw (uke) is taking a breakfall (ukemi) to safely reach the ground.
