Sleep on is a phrase on social media that is used to encourage others to pay attention. When a person asks you to not sleep on something, it means they want you to give it deserved attention. It can be a song, animation, news, or anything on the Internet.

Another meaning of this phrase is not to pay attention to something. A person is considered sleeping on something when they aren’t paying attention to the other person. It can also be used in a sentence when someone is asking for something urgent or needs you to be attentive.

Example

For example, if a pot is on the stove, you must be attentive, so a person might ask you not to “sleep on” it.
