Fionn

Some ginger fella who thinks he’s unreal at hurling but is shit and is bazzas bitch. He plays for boden which are by far the worst team in Dublin. He has a red piece of broccoli on his head that looks shite. He sometimes tends to put on a nacker accent despite him being from Knocklyon. He also is sexually attracted to children and kissed a fifth classer while he was in second year. An all round dodgy fella if u ask me.
