"young, dirty monks not accepted"

Something like that?

What's the name of your friend - Jesus?

Thanks. I think "not accepted" must be a better natural expression of native English speakers than "no" since you are a native speaker. But about "monks", I guess you might be misunderstanding. 僧 means indeed monks and 若 means indeed young, then it makes the word 若僧, but when we say 若僧, it doesn't mean young monks. It means general young people and the word has a nuance which like when the bad elders get mad at young people's rudeness, they say like "Hey, 若僧".
Maybe "young, dirty" might be a proper expression though do you have a good slang that like those bad (actually good, but you know?) elders say? I thought "worldly" might pinpoints the nuance but it seemed that the word has positive nuance.
The word シャバくさい doesn't have positive nuance. If the word "worldly" had only negative nuance, I think the word can express the nuance of the word シャバくさい. btw if we say シャバくせえ, the word gets more aggressive feelings. Obviously he is fed up with certain kinds of young (not just young people though) people's rudeness or bad habits or something like that when he says シャバくせえ. Sorry but as supplement, シャバくせえ sounds urban elder people's slang. Specifically Tokyo-born people. Do you have an idea of it? I have studied it sometimes quite seriously but I didn't get it. This is a good opportunity. Thanks. But I am not sure if I could explain the nuance of this word.
