What does TBF mean?
TBF is a texting and social media acronym that can mean to be fair or frank, as well as throwback Friday. Throwback Friday is a term that refers to posting or recalling something from the past, often from one's personal history, such as a grade school photo or wedding day memory.
But, it's unclear why you wouldn't just use the more popular and alliterative "#flashbackFriday."
