👀 

1. Emoji is commonly used to indicate that someone is suspicious. It may also reveal that someone is being inquisitive or trying to obtain information that is not their concern. It can also be used in some cases as a means of stating "I see you" or drawing attention to someone's activities. The meaning of this emoji might change based on the environment and the connection of the persons participating in the conversation.  

2. In my dictionary, the meaning of 👀 is to hold a skeptical attitude towards something, or after a friend has said something, express curiosity and want to continue to ask more.

3. In texting, the eyes emoji, or 👀, is usually used as a reaction to something attractive, like a photo of the person you're texting with. The eyes can also mean that you're curious about something, for example when you're prying into gossip or any type of info.

E.g. "I heard John got a new girlfriend 👀"

"Why were you up so late last night? 👀"

"I don't trust him, something seems off 👀"

"She's been acting strange lately, 👀 I wonder what's going on"
