coon's age Idioms  

1. Also, a dog's age. A very long time, as in I haven't seen Sam in a coon's age, or It's been a dog's age since I went to the ballpark. The first phrase rests on the mistaken idea that raccoons (“coons”) live a long time. The variant may reflect a similar assumption but the true origin is not known. [c. 1835] Also see donkey's years.

Sensitive Note

Coon is a shortened form of raccoon. Although a wild raccoon survives only 2 or 3 years on average, the phrase coon's age arose from the mistaken belief that these animals can live a long time. We still use the similar expression donkey's years, but coon's age has declined in use because coon is also a highly insulting term used to refer to a Black person.
