hyperbolicsyllabicsesquedalymistic 

From the album 'Hot Buttered Soul' by Isaac Hayes. The LP held the number 1 R&B album spot for 10 weeks in 1969.

According to a comment on the lyrics (//genius.com/1108119 ), this word was made up by Isaac, and -start quote from Damian v B. (//genius.com/Dyazz):

This word itself doesn’t exist of course, but it does include a few other words:
Hyperbole; exaggerated.
Syllable
Sesquipedalian; a long word with many syllables.
Mistic
Conclusion: Isaac uses a lot of unnecessary long, mystic words.

-end quote

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.
