There are several synonyms for the phrase "gets on a technicality." These include "exploits a loophole," "manipulates the rules," "takes advantage of a technicality," and "finds a loophole." This phrase is often used when someone is able to escape punishment or consequence by using a minor detail or rule to their advantage. It can be frustrating when someone is able to get away with something due to a technicality, especially if it seems unfair or unjust. However, it is important to remember that rules and regulations are put in place for a reason, and sometimes they can work to our advantage or disadvantage depending on the situation.
