What stalk do you secretly observe? Do you have an expression pack?

Stealth observation, an online buzzword, refers to observing something when others can't see it. This word is widely used in online chat, with various facial expressions, usually used as a cat's expression, which is very interesting.

Secretly observing this passage first came from the movie X Party on the Internet (as everyone knows, for example, the movie Qing Party worships Helan Qing).

"secretly observing and being skeptical" is widely spread.

Later, because of the high usage rate of the word "secretly observing", it was taken out and used alone. After that, the pillars of the expression pack have launched their own versions of hidden observation.

Usage:

When others speak freely, they want to join but can't say anything.
