Taking an action with no thought for your own safety or credibility in order to save a fellow gamer from certain doom/discovery/failure. A selfless act of friendly and much-needed help.
In this instance "gamer" means one who is out attempting to have fun, often by meeting/pulling/hooking up with people in bars and clubs etc. Although this really could refer to anything in which one acts to help a friend in an unusual situation, such as distracting an angry husband while a friend makes his exit, or quite possibly negotiating with a Colombian drug cartel.

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.
