When someone stretches the rules, they are bending them or being flexible with their interpretation. This can be seen as a type of cheating or unethical behavior, but there are other ways to describe it without using the phrase "stretched the rules". Some synonyms include: circumventing, bypassing, sidestepping, manipulating, exploiting, taking advantage of, flouting, ignoring or breaking the rules. Each of these words implies a slightly different degree of rule-breaking, from minor infractions to more serious offenses. No matter how you describe it, stretching the rules is generally frowned upon and can lead to consequences.
