You walk up to the one who offended your honor, slap him across the face with your glove, and challenge him to meet you on the field of honor of your choosing; usually at dawn. When he arrives at the designated dueling field you are hiding in the bushes or behind a tree, from which vantage point you riddle him with bullets. Just make sure you get there first in case he knows this protocol.
