A "disorder" found in kids (mostly). Here are the symptoms:

# often loses temper
# often argues with adults
# often actively defies or refuses to comply with adults' requests or rules
# often deliberately annoys people
# often blames others for his or her mistakes or misbehavior
# is often touchy or easily annoyed by others
# is often angry and resentful
# is often spiteful or vindictive

Pft! It's not a disorder, just bad parenting.
OMG! Honey, look at this article on ODD! It turns out our little obnoxious shit, Billy, is actually THE VICTIM here; of a horrible disorder! Poor Billy!! :\
