canniversary 

The yearly celebration of a person's first time trying or enjoying cannabis in some form. Sometimes celebrated by sharing one's cannabis or paraphernalia with members of their smoking community (reddit.com/trees, for example). Can also be celebrated with cannabis-infused space cake with candles.

Also, just another reason to get together with your stoner friends and get baked. Not to be confused with 4/20, the annual holiday that celebrates pot culture in general.
Miles invites his stoner circle over to his house every year at 4:20 on July 5th to celebrate his canniversary with them. They usually bring him gifts of rolling papers, a dub sack, and next year, they're going to Amsterdam for his canniversary!

Word of the Day on October 4, 2026
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.
