“RTFM” is an acronym used in online conversations and text messaging. It stands for “Read the F***ing Manual.” It’s used as a suggestion or a polite way of saying “read the instructions” or “read the documentation.”
However, the word “f***ing” makes it a vulgar and impolite way of making this suggestion.
As a parent, you may come across this term in your child’s messages and want to understand what it means. If your child uses this term, they are likely frustrated with someone or something and are suggesting that they should take the time to read the instructions or manual to solve the problem they are facing.
