Luffy wankers are just trolling.
That's the difference between Luffy and Zoro wankers:
Zoro wankers believe most of the crap that comes out of our mouths, fuck, I still believe in ZKK.
Luffy wankers are like Luffy, and like trolling people while making themselves laugh.
Anyone who actually thinks Kizaru is ducking Luffy here is crazy. Kizaru has three objectives, to secure York, the Mother Frame, and kill the rest of the Vegapunks. Luffy is an obstance to him, not an enemy he needs to defeat. Of course, defeating Luffy would be ideal. At this point, it's obvious Luffy is too fast for Kizaru to ignore him and still get the kill on the Punks. Kizaru at least needs to push him into cooldown.
Unless Sanji decides to actually, you know, do something.
