Screensdropping

The word eavesdropping first appeared in the English language in 1487, and then in English law in 1641. It gets its name from people who would stand so close to a home's eaves that they could hear a conversation inside.

In my third attempt at adding a word to the language, I am updating eavesdropping for the present day: screensdropping -- when a friend or coworker stands close enough to your computer screen to see what it is that you're doing. A major office faux pas. Use it every day.
