The definition for F.I.O. is Fart It Off. First known use in 1963 in Colorado. When a situation emerges over which you have little reasonable control just Fart It Off.
When my boss decided to chew my butt today for no good reason I decided to just F.I.O. and do my job.

Fio
"Fap it out"

The pivotal part of any decision making process, in which you must masturbate to flush your body of all sexual influences, in order to clear your head and think critically about something. To be used specifically before calling ex girlfriends.
Example 1:

Person A: "Dude, I've been thinking about calling my ex girlfriend and trying to get her back"

Person B: "I don't know what to say man. Just Fio and see how you feel"

(one fap later:)

Person A: "Yeah man I Fio'd and thought about it, I'm soooo glad I didn't call her."

Person B: "Good thing you made sure to Fio before you did something stupid"
