Logomachy: a war of words. Someone who fights with words instead of actions is a
logomachist.
"The logomachy of the presidential debate escalated to battery when Hilary Clinton, in a fit of Brandi Chastain-esque excitement, ripped off her shirt and began kicking Barack Obama's head like it was a cheap soccer ball."
-machy (war) is a great root to make neologisms from. For example, the common cartoon cliche of two fencing swordfish could be referred to as
ichthymachy. A more hifalutin' title for George Lucas's famous six-part sci-fi movie series would be
Astromachy.
