Blah, Blah, Blah Day is observed on April 17, 2018 April 17, 2017. The day is an impulse to do get the things done, which people have been nagging you to do. Blah, Blah. Blah Day is a chance to quit smoking, lose weight, vacuum the car and so on. It concerns all those uncomfortable topics in your mind you just cannot stand anymore to deal with. There are some things people never get tired so reminding you to do.
The only way to stop them annoying you is to take Blah, Blah, Blah Day as a kick-off moment to get things done. Mute the blah, blah, blah by eliminating the topic that it is about. Get yourself vaccinated, start a piggy bank, clean your laptop keyboard and call your aunt! By the way almost all languages have a pendant to the English blah, blah, blah like Blablabla in German, French and Spanish and falan filan in Turkish.
