A nervous system disorder involving the inability to prevent oneself from interrupting conversations they’re not a part of in an attempt to offer corrections on the subject at hand, but fail to provide anything of value because they actually know nothing of the subject.

A behavior commonly associated with period nazis in the SCA and other medieval-recreation societies and LARPs.
Madus as they are used in the Amtgard LARP are hardly recognizable as "actual" madus, yet you'll often see players correctifying each other about what "real" madus should look like.
