However, people have made up other things that can stand for FYI. For example "Fuck You Idiot". But, that's a bit pointless if you ask me. Saying the whole thing has a grander effect.
Prince Charming: FYI, not my fault!
-Fuck you idiot!!!
-What the hell?
Lisa & Bart together- "D'oh!"
An e-mail may be forwarded and in the content you can write "FYI" and the reader should then scroll down to read the remainder of the e-mail.
Can be mistaken for "For your FYI" - this is misuse of acronym.
Misuse: "For Your FYI it is our boss's birthday today" - wrong.
