This is the motto of the United States and is seen printed on its currency. A de facto manager might be a regular worker who has stepped up to keep the business running after a boss quit and wasn't replaced. This term is used to describe someone who does a job despite not being officially in that position. "Summa cum laude" is even better, with the highest honors. This is often added to diplomas to indicate that a graduate has earned honors by getting good grades along the way. It encourages people to think before they buy something, because they will inherit any problems or expenses with their purchase. This warning is so important that it's common to hear it in both English and Latin. The original YOLO (you only live once), it was later made popular in England by 17th century poet Robert Herrick. This philosophy was originally coined by the Roman poet Horace to encourage people to live life to the fullest. Today it's used to describe anything real or authentic, as in “this painting is a bona fide Picasso.” This adjective originally described someone bargaining or working in good faith, meaning they could be trusted. For example, “the radio station played the number one song ad nauseam.”

This is used to say that someone or something is repeated too much - to the point that you're getting sick of it. You'll often see Latin still used in inscriptions or used as an organization's motto, but you may also be surprised how often it crops up in day-to-day use.
