What your parents used to call any videogame system when they didn't want their friends to know that they know what it is called.
Mother- John, quit playing that "Intendo" and come meet your great aunt!
John- Mom quit calling my PS3 an "Intendo" because you know what it's called!
Mother- Oh I've no idea what a PSsomething is... John doesn't know what he's saying...heh heh.
Aunt- Well, then you really are a prisoner in your home because even I know what a PS3 is and I'm 87 years old honey.
