DAD: Speaking of the difference between sending an email and posting on someone's wall, what's the deal with OIF?*
ME: OIF?
DAD: You know, Overintense Facebooking!
ME: ... is OIF a real term, or something you made up?
DAD: I mean, I made it up.**

*pronounced "oyyy-ff."
**also made up by my father this week: "vs;sri" - "very short; so read it," a direct and kinder response to "tl;dr."
