Babelle
A person who talks nonsense and tries to sound smart but ends up being a dork. They say things like 'hello' and 'goodbye' like they're important.
My Babelle said, 'Hello, fellow human beings,' and I knew he was a dork.
My Babelle tried to explain quantum physics and I fell asleep.
My Babelle said 'babeling' and I thought he was spelling.
