Laffite's whole design concept screams "tap dance".
His wings apparently replace his arms, leaving only his legs free to use in combat.
Similar to how Marco fights.
Even tho he also attacks using his hands, like during "Blue Bird", which could also be the case for Laffitte, since i believe his "walking stick" might be a weapon like Brook's
So since tap dance is obviously a dance and that Sanji (and some of his opponents) fights in such a classy way to the point it also looks like a dance, its something that could be expected...
