In popular media culture, when you have three similar things happening, then it automatically becomes transformed into a ‘thing’, a trend, something to be imitated and repeated and reported on until everyone gets sick to death of it.
The latest that that I noticed is the use of hybrid names to describe high-profile celebrity couples. As far as I am concerned, it became a thing yesterday when I noticed the use more than once of the term ‘Kimye’ to denote Kim Kardashian and Kanye West. I recalled that earlier we used to have Brangelina and Bennifer, so this is now officially a thing. I find these things to be highly annoying, the same reaction to when the news media coin hybrid words based on apocalypse and Armageddon to describe severe weather or other major events.
Of course, since my following of celebrities tends to be limited to the headlines on Google News, there may well have been other cases and that this became a thing a long time ago without my noticing. I am sure readers will clue me in if that is the case.
