英语好的来一下

I'm shit-head!(asshole)!keep away (from me)!

嗯。。。如果无奈的语气的话，（比方找借口来拒绝某个人）这么说会比较好
I'm just a bastard，so you just leave me alone, Okay?

如果是很愤怒的话，那就这么说！
I'm a bastard! I'm a son of a bitch! All you gotta do is staying away from me!

嗯，如果还有什么别的情况的话，不妨留言给我呀~~~~
呵呵。。。因为我还可以问我的外教的哦~~~~~

I am a jerk, leave me alone!

最近看的美剧里的，应该挺地道！

呵呵

I am an asshole,get away from me!

I am a bad guy. Let me alone.

I am a bad guy~Go away~
