RTFO

Abbreviation for 'Rest of The Fucking Owl'. After a Reddit group by the same name. Used to tell someone that they left out key information or steps.

Person 1: Explaining how to change a tire. "Take the flat tire off, get your spare, and put the spare on in it's place."

Person 2: Where's the RTFO?
