Snitching

The practice of snitching is when someone secretly tells an authority figure that someone else has done something bad, usually in an attempt to stir the pot and cause trouble. In the case of Papp/Dom's Fat Lore, this usually is due to someone being too butthurt about something, leading to them complaining and whining to attempt to get their opps in trouble.
In real life, this practice is somewhat acceptable. While snitching is looked down upon in places such as prisons, in many situations, it is generally the morally right thing to do. If your balding 40 year old uncle rapes a 12 year old, you should probably snitch on him. Unfortunately, this has been subverted by many bitch ass niggas, who usually do this due to being butthurt rather than due to an actual threat on their life or someone elses.
Examples
Chippy
Chippy can be considered the original snitch and would snitch during the Fall Arc. This was because BLau and Papp bullied him on Discord, which was too much for him to bear. He also thought that the Paulina-Chan tweet was made by Paul and Blau, despite Blau not being mentioned in the twitter account. This led to him reporting them to the school, but the school probably looked at him like a retard because he had no real evidence, due to BLau's discord name being some variation of a term like "gayniggafartdicklifter69" and not having real info in it. Papp also lived in Hunterdon, so there was nothing anyone could do, and there was no proof Paul did anything either. As a result, nothing happened with this, but it did emphasize Chippy's role as a bitch.
Papp
AaLyiah Crate
AaLyiah crate is a fat 300lb slob who attends West Essex High School and smells like complete shit. After Christian Castrovinci interacted with her, he thought it would be comedic to make an edit of her as the fat ass angry bird and call her smelly in the edit.
Damien Williams thought this was hillarious, and being the absurd sigma he is, sent this to her. Aalyiah and her fat smelly friend group tried to snitch on Damien and anyone that followed him. Unfortunately for her, the McDonalds must have gotten to her brain, because this would not actually be any proof to punish anyone. Damien Williams lived in Marion Virginia, who did not have the same bullying laws as NJ, because they are based southern drug enthusiasts. Dom's Fat members following Damien would also not constitute proof that they made him send the picture, so it ended up with her just being a smelly fat piece of shit and accomplishing nothing. Mr. Emering probably found the edit funny, but didn't say anything out of fear of losing his job.
