Sometimes, things really are serious.

The stock situation -- and StockPhrase -- is a MatterOfLifeAndDeath. The ObstructiveBureaucrat is prone to get this flung in his face. Although considerable variation is allowed in the face of different situations: whatever the problem is (or problems are) can be used instead.

People on your side who do not take it seriously -- such as the CavalierCompetitor -- may also be told "This is NotAGame."

When the stock phrase is used erroneously, it's probably an example of SeriousBusiness.

Not to be confused with the 1946 David Niven movie ''Film/AMatterOfLifeAndDeath'' or the 2006 Music/IronMaiden album of the same name. ''Definitely'' should not be confused with the Franchise/WallaceAndGromit short, "WesternAnimation/AMatterOfLoafAndDeath".
