So there's something off about the new guy. You want to keep him on his toes, let him know that he can't be at home just yet. You want him to know that you'll be watching him.
The wonders of nonverbal communication make saying all this without wasting your breath possible. Just perform these two simple gestures. Point to your eyes, preferably using the backward V-Sign: "I AM WATCHING" and point to your target: "YOU."
Details can vary, using different fingers when pointing at different things, but this is how you generally tell someone that you are watching them. Though generally a threatening gesture, it is known to have at times been used in a friendly or reassuring manner as well; communicating something to the effect of "I'll be seeing you", "I've got your back" or such. In many sign languages, the same gesture from one side of the face (not centered) translates as "see" or "I see you."
Examples:
- The E-Trade Baby makes the gesture, possibly a reference to Meet the Parents.
- The Burger King does this in one commercial during a news conference, while his spokesperson dismisses every question. The last question gets this response from the King.
- Mechamato: After the Cone Konchos are defeated and forced to clean up their mess, their boss expresses that they're still a threat by pointing at his own eyes and then pointing at Amato, glaring at him all the while.
- In the Tiny Titans/Little Archie crossover, Robin speculates (correctly) that Mrs Grundy is married to Solomon Grundy. Later Solomon Grundy shows up and claims to have no idea what Robin is talking about regarding supervillainy. On his way out of the classroom he gestures at Robin angrily.

- Monkey from Kubo and the Two Strings is mistrusting of the new crew member Beetle and does this gesture to him to send a message.
- Puss in Boots: The Last Wish has the Wolf putting two gold coins on his eyes before doing this to Puss. It's also a foreshadowing for those who know a little about history; the Ancient Greeks placed coins over a corpse's eyes before burying them, as they believed that the dead needed the coins to pay for the services of Charon, who ferried them to the afterlife. This foreshadows that the Wolf isn't any ordinary wolf, but Death himself.
- Seen in The War of the Worlds (latest version), with two soldiers.
- Robert De Niro's character does this to Greg Focker in Meet the Parents and its sequels. It even provides the page quote at the top.
