Some years ago a caller became very offended when our tech support person used the word "cheat" when referring to the manipulation of the text towards a lower or higher page count. The caller thought the tech person was accusing him of some dark moral transgression, but the term "cheat" as it's used when discussing a script's pagination is common and those who do it are not -- nor should they be -- shunned by decent society.
We have, however, intentionally limited the number of ways to cheat the page count. Producers, assistant directors and unit production managers need to be able to rely on roughly one page per minute and if too much or too little text is on the page, this standard production convention is out the window and the script might as well not be formatted.
