There are more cutthroats than I expected! Some are still in hiding and some are waiting for the right moment to delight and offend.
Recently, the most fertile cutthroat fields have been surname dictionaries and board game names and cards (many suggested by @snapshot_reviews). If you see capital letters in this list – it’s either a surname or the name of a game.
The attached PDF has 33 pages of cutthroats and their earliest year of attestation.
