He ís just showing himself his own level of intelligence by how he is expressing his opinion. Level 0 of intelligence and of education. Maybe he is not filthy by the look of wearing a cheap costume but by the way he is talking he is surely filthy on the inside and that is hard to clean. I am Romanian living in a Scandinavian country, Iceland, and I am not here to steal anything, I am here to study and I am the second first foreigner person in law school. I am sure that this guy is 10 times worse and filthier than me any many others that could teach him a lesson.
