Every Saturday I’ll give you a couple of idioms to learn. An idiom is a saying or phrase whose meaning cannot be taken from the literal meanings of the words.
donkey’s years/coon’s age: a very long time
Example:
How are you doing, Sam? I haven’t seen you in a coon’s age.
dumb bunny: someone who is stupid or naïve
Example:
Don’t be a dumb bunny. Be sure you take your cell phone with you when you go out alone after dark.
