I'm not sure which scares me more
What Kenpachi says here is basically what most Bleach fans would like to yell at Ichigo on a regular basis for the amount of ass-whuppage he seems to take before he remembers that, hey, he's the Main Character, and is therefore supposed to be badass and not quite so full of fail.
I take the fact that Kenpachi said this in the new chapter to mean one of two things:
1.) This may be a hint that Kenpachi is gaining a Deadpool-like ability to break the 4th wall, or
2.) Tite Kubo has started to read what's posted on Bleach fansites. ...Although that might explain a lot, actually.
