Gnomenclature is the science concerning the production of electricity. Inside of wires there are thousands of tiny gnomes awaiting command to begin high-fiving. When you flip a light switch on, it triggers a chain reaction between the gnomes. One high-fives the other and a domino affect begins, carrying exponentially increasing gnome high-five magic along a chain of microscopic gnomes, eventually leading to the bulb which is set to continuously run by a gnome performing interpretive dance inside the filament.

When you're being horny (especially around friends) and as a result shame ensues.

gnomenclature (n.) - A whole collection of words, speeches, and soundbytes intended to support a business plan that mirrors the Underpants Gnomes' business plan.
