From the Foreword: Dear Reader, If you're like us, you've faced trouble from bullies. For example, I was once pinned down by a young lad who repeatedly asked me why I was hitting myself, when he knew full well that I had temporarily ceded hegemony over my hands and forearms. I tried to explain it to him, but he didn't seem to comprehend. In retrospect, I can only conclude that my explanation was not articulate enough. To that end, I and Phil Plait have teamed up to create precisely 128 insults designed to weaken the resolve of aggressors, while educating them in their primary field of interest. Whether the person pummeling you is a student of mathematics or belles-lettres, we have the right words for the occasion. Zach Weinersmith PS: In the highly likely situation that the person pummeling you refuses to cease his aggression until he understands the meaning of the insult, we have also provided an appendix in which the insults are explained.
