To make a catastrophic, horrendous error or to be woefully unprepared for a big event; especially when the
mistake / lack of preparation could have been easily avoided.
The essence of ‘Borising’ is in the fact that it is unbelievable that the error occurred, and that an
average person of relative competence could have identified the problem with ease, before it happened. If the
mistake was caused by a genuinely unpredictable event, then it cannot be described as Borising.
Can also be used as a noun, referring to a easily preventable disaster of Biblical proportions. Again, it must be
one that simply didn’t need to happen, and a normal functioning human being could have easily prevented.
