my memory might be tricking me, but I think it started from "Bitcorn"
That would make this the first occurrences:
Dude.. its called microphone! No need to shout the voice through the internet
Bank academic guy doesn't know how to use a mic!
Bitcorn bubble!
Edit: Single digits! MY FUCKING EARS!
Bitcorn, the coin that will hit single digits by June! Guaranteed.

I recall it starting in 2013 with a mispronunciation by professor Mark T Williams of Boston University. It led to him being known as Professor Bitcorn. I haven't found the actual quotation yet but I'm sure it's out there somewhere. For now I've had my piss and re-hydration and I'm going back to bed.
