Ignore is a command in your social panel. You can add someone as a friend in this panel, which means you're notified when they log on and off, or you can ignore a person who is harassing you or just being annoying.
A duel is when one person on the same side (Alliance or Horde) asks another person on the same side to fight. Neither character dies, but the characters fight until one is down to no health. Then the duel is over and the players go their separate ways.
When someone is invited to duel, the invitee has the option of accepting or declining. Sometimes a player will ask the same person to duel over and over again, hoping to annoy them into an "accept duel."
So a couple of days ago I was in one of those inexplicable girl moods -- my hormones were out of whack and even though I'd had a productive day working on my novel, I was still sort of depressed and wanted to curl up with a book after leveling with friends on Warcraft.
So we ran into town, winding down for the night, and I decided to sell a few things and check my mail. I was especially anxious to get off because of my dorky mood, but this random guy decided to ask everyone in my party to duel. This was after some random guys asked all of us (one at a time) to instance with them.
So the THIRD time this goober asked me to duel, I whispered, "I'm PMS-ing. Please leave me alone?"
He did. Thank God.
Likewise, yesterday I was asked three times in the first ten minutes to instance with random people just because I was playing my priest. Ugh. I was trying to level so I could instance with my friends later this week and attempt my new role as damage-dealer instead of healer -- not so I could spend all my mana watching doofuses get themselves killed and then yell at me for it.
I'm afraid my rejections have been getting more and more brief due to this excess of bugging. It used to be "I'm sorry, I'm doing ______ instead. I just can't." Then it was "No thank you." Now it's just "No." If you know me at all, forcing me to be as brief as "no" actually means "No, and FOR THE LOVE OF GOD leave me alone."
Lucky for people like me, there's an addon called AutoDecline.
"if you want to put people who send random duel invites on ignore, simply add /ignore $player to the list of duel actions and it is done for you"I think Thesden has it set to ignore people when they ask to duel him a third time in a row. Bliss. Just bliss.
