terribilism

The starting point for this word is the term enfant terrible which dates back in British English to the 1850s and was applied to a child who embarrassed their parents with ill-timed remarks.  Later it was applied to adults who were, in their speech or behaviour, unconventional to the point of shocking other people. Such displays have come to be associated with precocious talent.

We have seen the enfant terribles of the sporting world, McEnroe being held as the prime example, followed by Nick Kyrgios in our own part of the world.  

There are examples of the ad-hoc formation enfant-terrible-ism for the character or quality of being an enfant terrible. The hyphen before the suffix is needed here to show that it applies to the whole compound. But more recently we have the shortened form terribleism.  Apparently we need strong anti-terribleism  legislation to keep our national reputation safe from the likes of Nick.  A paint-ball venue has in its list of Do’s and Don’ts that any sign of terribleism will be met with swift eviction.

There is not a lot of evidence of use yet but terribleism may be rising in frequency.
