A shmegeggyface is a person who uses words that are firstly and clearly not defined as acceptable for English usage. A smeggeggface begins sentences with words that don't need to be said and undermine intelligence.
"I hate people who use the word 'firstly.' I have no objection to 'secondly', but I don't like 'thirdly' and obviously anyone who says 'fourthly' is a shmegeggyface.
