My MA is already a verb. Fencing.
But it makes no sense in modern terms "Back off or I'll fence your a$$"
But 'sword' works great. "He was starting some sh1t so he got hisself sworded."
(Where would I be without HomestarRunner, and especially Trogdor?)
Or, of course, 'Bah. Foiled again!'
And you can have all sorts of fun with the b4st4rd sword and the rapier...
