I competition--usually between two friends--to warn then to 100% on AIM. The key to warning wars is being fast with your mouse and having several different screen names from which to warn your victim. For, if you're warned to 100%, you can't send IMs quickly.
"I had a warning war with Peggy last night and warned her from all 12 of my screen names. I won!"
