The nickname of the NY Mets' manager Jerry Manuel, commonly used by Mets fans out of frustration and confusion directed at Jerry's managerial decisions and outlook on the team. During post-game press conferences, Jerry is known for laughing hysterically in a demonic tone at times (even when the team is struggling mightily, thus displaying his clown-like nature). He also has trouble forming coherent sentences as he frequently says, "Um" and "Uh" to the extent by which only few can understand what he is trying to explain.

A buzz word being used to refer to creators and influencers forming or encouraging unhealthy relationships with their fans. Usually used in the context of young audiences feeling they have a relationship with the influencer due to the huge amount of the influencer’s content they consume. The influencer in question, however, is unaware of the fan’s existence other than the general knowledge of having fans. Common examples include Dream and his stans. These relationships are exacerbated by the influencers confirming they have more than a creator-to-viewer relationship.

The word is circulating due to various YouTube essays about the phenomenon using the word, and therefore people who enjoy complaining about influencers repeating what they heard in the video in any comments section they can find.
