Ogle

The American Heritage College Dictionary defines ogle as, "v. To stare at... to stare in an impertinent, flirtatious, or amorous manner... from Low German oog, oge, eye." This is such an amazing way to say that someone is staring! And the etymological definition makes complete sense; you are using your eyes to check someone out. I chose this word because Valentines Day is coming up and I think everyone should be doing more ogling!
