Definition: A cave dweller or a person who is considered to be old fashioned or out of date in their views.
We accidentally hired a troglodyte.
When we casually mentioned ‘Outlook’ and ‘send’ in a conversation, he jumped away from the computer. Before we could stop him, he sent forth a pigeon with a note that said ‘Cool. See you then.’ attached to its foot.
Will just have to tell him that the ‘e’ in ‘email’ stands for ‘eagle’. Maybe he will be alright?
