Translation of "Bloke" in Japanese

I don't want to talk to that bloke ever again.

あんな奴とはもう二度と口をききたくない。

Sorry, he is a troublesome bloke. I shouldn't really be saying these things to people though.

ごめんね、めんどくさいやつで。本当はこんなこと誰にも言わずにいるべきなんだけど。

Now that I think of it, I've been asked to look at a haiku he'd written by the tipsy bloke sitting next to me on the train.

そういえば、電車の中で隣に座ったほろ酔いのおっさんに、自分の俳句を見て欲しいと言われたことがある。
