A person who peeks through out a window looking at shadow things, the neighbors, or other random stuff while trying to remain unnoticed.
I heard a noise outside, so I quickly rushed over to the window to peak out my curtains & a shadow person was window peeking back at me. One of us needs sleep. Damn window peekers.

One who glances without permission at the computer screen of others, usually done in public and to laptop users.
"I was trying to log onto Facebook but there was a screen peeker lurking behind me so I had to close my screen and walk away."
