Thin purple line 

Term coined on TwitchTV related to the concept of charity provided to other streamer's when they fuck up due to self interest or their own goals (sometimes positive and noble). The desired outcome is to maintain positive relationships with larger viewer networks in order to grow their audiences due to some moral expense.

It is an analogy for the Thin Blue Line in police. Crossing the Thin Purple Line will often result in shit for streamers from parasocial pushback as well as ostracization.

Term originated by SeanDaBlack in late 2023-early 2024.
