Diet Solo
A Diet solo stan is a heavily biased person who claims they are a fan of a group but in reality they are very close to being a solo stan. They usually follow mainly solo fanbases of their bias, lots of akgaes and believe victimising agenda and false information like screenshots out of context. Many of them give up on being a fan of the group at some point after being exposed to solo stan narratives for a while and join them, while speaking ill about the fandom they once belonged to.
A Diet solo is someone who is very close to becoming a solo stan/akgae. They usually only support causes related to their bias and don't see anything wrong with supporting the agendas of solo stans, even if it harms the group their bias is in.
