ogle
To stare at someone in a rude, uncomfortable way.
To ogle means to stare at someone in a way that makes them uncomfortable, usually with too much interest or admiration. When someone ogles, they're staring obviously and inappropriately, often making the other person feel awkward or disrespected.
You might read in a story that a character ogled the dessert table at a party, staring hungrily at all the cakes and cookies. But more often, the word describes how people look at other people in a rude way. If someone ogles a classmate's new sneakers, they're staring so intensely it becomes uncomfortable. If a character in a book ogles someone they find attractive, they're staring in a way that's creepy rather than friendly.
The word has a negative feeling to it. A respectful glance or genuine compliment feels completely different from ogling. When you notice something interesting about someone (like cool shoes or a clever project), a quick look and maybe a kind comment shows respect. Ogling crosses a line into rudeness because it treats the other person like an object to stare at rather than a person who deserves courtesy.
