If I'm correct, this is the first two actions for the 'triple jump' the last being: 'jump'. I assume Yuugi's outfit (looking like a gym outfit) is meant to imply that her knockout in 3 steps is basically a triple jump. which is actually kind of funny.
I don't see anything "stupid" clever about that though... is it just me or are several posts being put in the pool without meeting that "Stupid" qualifier?
