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.
sell like hotcakes: sell very quickly.
Example:
This new smartphone is selling like hotcakes.
buy out: buy another company, or at least buy a controlling share
Example:
Have you heard? The bankrupt snack cake company was bought out by a major retail brand.
