Flexibalise, present tense of flexibalised, means to make something flexible. The etymology is unknown, though it sounds like a French-speaking speech-writer using the word flexibilisé.
This word was added to the English Dictionary (Bubble Version) after the 2020 SOTEUSOTEU (short for Sound Of The European Union) is the most successful musical of the EU Bubble. It is performed once a year in front of the whole European Parliament, usually in Strasbourg, though SOTEU 2020 was held in Brussels because of covid pandemics and because almost nobody wanted to..., held by President Ursula von der Leyen.
