Kosta

Kosta is a Greek dude who loves Greece so much. He often makes wierd remarks about people’s skin colours, but is very effective at shutting down any notions that he is a racist. He is pretty hot but bad at pulling bitches due to his annoying personality.
Damn, Kosta made a sly remark about my skin colour last night.
Yeah, he’s like that.
