Origin of Last One In is a Rotten Egg
While many assume the phrase derives from the literal agricultural reality of an egg rotting if left behind in a nest too long, etymologists point to a broader evolution. The term ‘bad egg’ or ‘rotten egg’ has been used since the mid-1800s to describe a dishonest or worthless person (originating from the practice of ‘candling’ eggs to check for spoilage). ‘Last one in is a rotten egg’ simply adopted this existing insult, using it as a harmless schoolyard taunt to penalize whoever is slowest to join an activity. It has been used since at least the the mid-1930s.
