Short for "only child syndrome." Can be associated with
selfishness, rudeness, laziness, and/or arrogance, but is not limited to these things. OCS may also be accompanied by strange/unexplainable side effects, i.e. excessive computer-nerdiness, knowledge of the names/charicteristics of people who do not know you, the need to bite inatimate objects or others, the need to snuggle with
those you have just fought with
, the urge to tickle/poke others for no apparent
reason, and many other habits that vary by individual.
