Fusi’s are the best kind of people, need someone to make you laugh bitch she’ll be there. Need some food, she’ll cook you a whole cow. Fusi’s are bad ass and don’t give any fucks for what people think. She is a fucking amazing person and just wants to vibe with everyone. She’s also crazy about those poly boys ^^. Go find yourself a Fusi and your life will be much better.
