The term 'stingy sort' is a combination of three words: MISER (5 letters), bee (3 letters), and PIKER (5 letters). A MISER is someone who is extremely frugal and unwilling to spend money, while a PIKER is someone who is similarly stingy but also cowardly. A bee is an insect known for its industriousness and ability to work hard for long periods of time. Together, these three words form a phrase that describes someone who is not only frugal and unwilling to spend money, but also works hard and is cowardly.
