African-American slang often creeps into general usage. One that is moving into such use is "twenty-four seven" as in "I used to be able to do it twenty-four seven". It is just shorthand for "twenty-four hours a day, seven days a week", that is, all of the time.

This phrase was unknown to me outside of the African-American culture ten years ago. Now it shows up in newspaper and magazine articles.
