A "Montana Blackburn" is when a man takes a shit early in the morning, but doesn't wipe his ass, then puts on tighty-whiteys. Late in the day, when he's having sex in the doggystyle position, he takes his shit-stained underwear and wraps it over her face, or across her mouth, and proceeds to fuck her while pulling on it.

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.
