俺、ペーパードライバーだから運転には自信ないんだ。電車でどこかに行こうよ。

I'd rather go by train. I have a license, but no real driving experience, so I'm not very sure of myself behind the wheel.

俺、甘党だけど、お酒も飲むよ。

I prefer cakes or candies to alcohol, but I do drink.

「実を言うと、俺、高所恐怖症なんだ」「臆病者っ！」

"To tell you the truth, I am scared of heights." "You are a coward!"

俺、早食いなんだ。

I'm a fast eater.

「宝くじでも買う？」「俺、ギャンブル運とか無さそうだしなぁ」

"Buy a lottery ticket or something?" "Well, I don't think I've got much luck with gambling."
