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.
hold one’s horses: wait, be patient
Example:
I know you’re hungry, but you’ll have to hold your horses – supper won’t be ready for another half hour.
holy cow: used to express strong feelings like astonishment, pleasure or anger
Example:
Holy cow, you guys are making so much noise I can’t think! Turn it down, ok?
