FN is an abbreviation for Fucking Namaste, and is typically used as the complimentary closing to an online message similar to "Sincerely Yours" or "Best Wishes." It is often used when the author wishes to convey a strong sense of clarity and purpose. The word "Namaste" is commonly used in India as a general-purpose respectful greeting (either hello or goodbye), however, it has become quite common in other contexts such as Western yoga classes.
Folks, we can no longer tolerate racism in this institution. So, tomorrow, we are closing our doors forever.
