My boss does this often. For example, when he talks about tooltips he calls them 'hoover statements'. This caused quite some confusion when he discussed 'hoover statement design' with an interface designer. The designer thought he was talking about the hoover states from the buttons (where the color changes when you mouse over it, or click on it) and proceeded to redesign the buttons in that interface.
But my boss gets a lot of things wrong - an 'overlayer' can mean a tooltip, a popup or an actual overlayer. A header & footer means stuff that is on the top of an interface and bottom of an interface (header and footer are usually used on the context of text makeup). He says roadmap instead of backlog, upscaling means 'improve the quality', clickpaths mean links, 'the road is ending' means that something is a dead end.
Conversations with him are quite tiring because he keeps making up new words on the spot or use words in an incorrect manner. I keep correcting him, or play clueless and ask him what he means. I tried to be nice about it first but now every time 'hoover statement' crosses his lips, I immediately say 'tooltip'. He is hurting his own business by confusing the people who work for him, but is very resistant to learning...anything.
