Similar to the common alarm clock it is designed to wake up the recipient; the main difference being that a book is used (as opposed to a shotgun) by a second person and most commonly with a great deal of force. It is similar to a cock slap except that the relevant genitalia is replaced with a large book.
Christoph was asleep in Geography so I used the old book alarm to get him up.
