The Post-it Note Fandom 

Share definition Flag
On October 31 2019, member Wonho left the South Korean boy group called Monsta X due to false accusation in efforts to protect the group from negative attention. Monbebe (fans of Monsta X) showed up to the Starship Entertainment building singing, crying, and writing messages of love and encouragement to Wonho on Post-it notes and stuck it to the building. This sparked Monbebe to trend hashtags on Twitter for months hoping to show support and get attention from the company to do better. “Post-it note fandom” was used as an insult from other fandoms to tease the efforts of Monbebe trying to get Wonho back... because frankly, a thing like that has never been done before. Once an idol is accused and leaves their company, much is not heard from them after that. Against all odds Wonho made his solo debut on September 4th, 2020 with his EP Love Synonym! Monbebe & Wenee (Wonho fans) couldn’t be happier.
Anti: Stupid Post-it note fandom, writing your notes won’t bring him back.. trending your hashtags won’t bring him back.. give up!!

Monbebe: he’ll come home just wait and see..

Months upon months later...
Wonho: *solo debuts*
Monbebe: Yeah the Post-it note fandom did that...

Boffin 

Share definition Flag
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
