An exultant yell usually delivered when hitting, completing,
winning, or when there is
boredom. The tone and volume is not unlike
something a character in Mortal Kombat would yell while hitting someone.
1.While in an
art museum,
running up to a Titian and punching it, yelling "CIDER!"
2.If nothing is going on, this is a
good excuse to run over to an object and "cider it".
