The shameful act of glancing at another player's section of the screen during split-screen video-gameplay to gain knowledge of their location or assets.

Screen Hawking

When a co-worker, or nosy individual, walks behind your computer/workstation, staring at your screen as they pass, to try and figure out what you're doing.

"I was working on my month end close, and Socially Akward Penguin kept walking behind me, screen hawking and mouth breathing"
