It's what one girl does to another girl who is sleeping with her man and she finds out

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.

To open handedley slap someone. Denote disrespect for the person being bitch slapped as they are not worthy of a man sized punch. Suggests the slap was met with little resistance and much whining

The literal and/or metaphoric slapping or whacking someone in order to knock some sense into them.

To slap someone (particularly but not necessarily female) who is being rude or nasty, perhaps screaming a lot (i.e., being a bitch). The idea is to get them to calm down and behave. It doesn't necessarily mean you really hit the person; there is such a thing as a verbal bitchslap.

As distinguished from the more common "pimp slap", a bitch slap is preceeded by ample forewarning and delivered with a flourish or exaggerated post-blow hip movements. Nonetheless, the blow is firm and may involve an open forhand or backhand.

A "pimp slap", to the contrary, is regularly delivered without announcement and oftentimes over breakfast at an IHOP, on a subway platform, or numerous other indiscriminately chosen venues. The blow is always, always struck with the back of ones hand as to do otherwise is bad form. And the hip motion that accompanies a pimp slap provides the torque to knock a bitch silly.

The kind of slap a pimp gives to his whores to keep them in line or punish them. However, it is most commonly used to describe an insulting slap from one man to another, as if the slapper is treating the slappee as his bitch.
