The former radio host and current Youtuber, John "TotalBiscuit" Bain, often finishes his videos with the phrase My name has been TotalBiscuit, thanks....
I'd never heard this expression before, and it sounds odd to me, as if it implied that his name changed after the show ended.
Is this just a very specific catchphrase? A common expression among radio hosts? Or used more commonly than that?
For instance, could I say it at the end of a scientific conference, such as "My name has been John Doe, and I presented you the results..."?
