I don't really have an explanation for how I ended up here. Blame TV Tropes if you must.
Explanation (as far as such things can be explained, anyway...): Apparently, the character who attacked the other (and sorta takes the place of "PC") has time-stopping powers, like the character Dio Brando from Jojo's Bizarre Adventures. And stopping time, throwing knives, and then dropping steamrollers on people like so-
-is Dio Brando's memetic signature move.
Who knows why, beyond the obvious "dropping steamrollers on people is kinda funny" aspect?
