Cartman next door
The boy/girl next door that thinks none of the other kids but him/her should have as much right to talk as him/her, which is why the Cartman next door never shuts the fuck up, but expects everyone else to. The Cartman next door always claims to want to give everyone a voice despite being the only one talking, thinking that they're all okay with somebody other than themselves being their own voices.
The Cartman next door likes to ridicule the other kids he/she is pretending to be friends with, though it's hard if not impossible to see how/why anyone would like or want to be friends with someone like the Cartman next door. He/she is as much of a loser as any other kid that he/she is always calling losers, and wants to look tough all the time, despite a lack of any real evidence that the Cartman next door waa ever tough at all.
