Is the term FR casual or formal?

The term FR is extremely casual and should only be used with friends and family in relaxed settings like via text message or on social media. This term is considered internet slang, and should never be used in professional or formal contexts like business emails, resumes, negotiations, letters, or other formal settings. Below is an example of a situation in which it is inappropriate to use the term FR, followed by a revised version of the same message. 

In this example, Kevin has received an email from his professor Dr. Cavic that accuses him of plagiarism on an exam. Kevin replies to the email and tries to defend himself.


Yo Dr. C,

U can’t be fr! I s2g I did not cheat on the exam, I wud never. IDK who told u that or what u saw but I promise I didn’t. I studied rly hard – I can even show u all the flashcards I made. Wat can I do 2 make u believe me???



Hi Dr. Cavic,

I must say, I am pretty shocked to be receiving this email. I can assure you, I would never cheat on an exam. I take your class and the topic of academic dishonesty very seriously. I am happy to show you all of the study materials I made for this exam; please let me know how we can work together to get past this, as I assure you, I did not and never would cheat on an exam or any other assignment. Thank you for your time.



In this serious situation, though Kevin is in disbelief, he should still make sure that he uses proper grammar and email etiquette to show his professor that he understands the seriousness of the situation. Text slang and internet abbreviations are never appropriate in this formal setting.
