Term used to describe an outburst of an individual who is very active minded who blurts out random things he or she finds comical. These are usually stated when a highly active mind quickly changes thought processes to roughly relate the joke to something that is happening at the current moment as is the case of those with Attention Deficit Disorder. These outbursts can be humerous depending on the individual or flat out stupid. Enism's typically are made out in public and often embarrass those who are around the individual.
