is the period lasting for a few summer months typified by the emergence of frivolous news stories in the media. The term was coined in an 1861 Saturday Review article.... In many languages, the name for the silly season references cucumbers (more precisely: gherkins, or pickled cucumbers)... all mean "cucumber time" or "cucumber season." The corresponding German term is Sauregurkenzeit ("pickled cucumber season").
The season of the cucumber is the time to write short fluffy things...

... like this list of the summeriest things, apparently. (Those things include sun, sun, sun and being warm.) (According to Google Translate.)
Unfortunately, that's the only use on twitter of this hashtag so far this cucumber season (and only the second this year to date), but stand by, there's two weeks left. What a beautiful language Hungarian is! And such wonderful people.
