KMI

Scene: We're all in the living room, Manny is playing Fable. I notice that today he is wearing his orange shirt.

Me: I see you're wearing the orange shirt.
Manny: Yes.
Tarik: Where did you get that orange shirt?
Manny: Georgia.
Tarik: Manny, what's another way of saying Georgia?
Manny: Georgia.
Tarik: Yes, but there are other ways of saying Georgia. Like by the initials. What are Georgia's initials?¹
Manny: ....KMI.²
Me: Huh? What the fuck is KMI?
Manny: .......I don't know.

¹ One of the jokes we like to tell repeatedly is how Manny has a fun time in or with GA. This has two different means. One meaning is Gay Alliance. The other meaning is Guy Assistant.
² Manny meant to say "KMA" as in "Kiss My Ass". What he ended up saying is "KMI", which is short for "I'm fucking retarded."
