Fake OT7 

People that claim to love all bts members equally but in truth it’s only valid when it benefits their actual bias. Most fake ot7 are hyung line stans that pretend to like ot7 but would throw ot6 under the bus for their bias. In other words fake ot7 are mostly solo stans that lie to gain clout or just acceptance in the fandom.
Example 1

stan: “I cant wait for Jimin’s solo projects”
Fake ot7:” jimin can’t write so I doubt he’ll release anything soon he’s good in bts :)”

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.
