What does “sleeping on…” mean?

If a person says “ya’ll sleeping on X”, then it means that they believe everyone is overlooking or ignoring whatever X is.

In other words, if someone is sleeping on something, then it means that they are failing to fully appreciate it.

This is a slang phrase that has become increasingly popular since 2017.

For example, imagine that your friends are sitting around in a group and discussing their favorite gangster movies. Everyone is listing off classics such as Casino and Goodfellas. Someone even says Donnie Brasco.

However, for some bizarre reason, nobody mentions The Godfather.

In this case, you might accuse your friends of “sleeping on” The Godfather.

Take the following example from rapper Meek Mill.

In this example, the Twitter user in question is advising everyone to stop “sleeping on” people who have good hearts. In his opinion, people with good hearts are rare nowadays.

Note that this slang phrase doesn’t have to be about a deep or serious topic. People will casually use this phrase when talking about things such as food, football, video games and even which department store they like best.

Twitter user @naythabrat clearly believes that people don’t appreciate Marshalls or TJ Maxx enough.

“Ya’ll sleeping on Drake.”

You might scoff at the idea of someone accusing people of “sleeping on” Drake when he is one of the most successful rappers of all time.

However, Drake didn’t rise to fame until 2010.

In other words, his mainstream breakthrough came two years after Randy Roper posted this tweet.
