Good egg
Meaning
A good egg is a kind, trustworthy, and generally pleasant person.
Origin
The phrase "good egg" emerged in the 19th century, drawing its meaning from the simple, everyday experience of cracking open an egg. Just as an egg could be fresh and wholesome or, disappointingly, rotten and unpalatable, so too could people be judged on their character. A "bad egg" was someone unreliable, perhaps even deceitful, embodying all the unpleasantness of a spoiled albumen and yolk. Conversely, a "good egg" was someone of sound character, trustworthy and pleasant, a clear, wholesome metaphor for an admirable person. The simplicity and vividness of the image quickly cemented its place in English idiom.
Examples
- My boss is a good egg; he always looks out for his employees and is very fair.
- Everyone loves Sarah because she’s such a good egg, always willing to lend a hand or offer a kind word.
