stick in the mud, old

A person who avoids anything new; an old fogy, not necessarily old in years. This expression, which presumably likens such an individual to a vehicle whose wheels are stuck in mud, has been around since about 1700. Thomas Haliburton used it in one of his Sam Slick tales (1843): “‘Well,’ said old Stick-in-the-mud, ‘what are you arter?’”
