Trouble understanding 相変わらずとぼけた奴


I'm having trouble understanding this person is saying. I understand he is
complaining that someone is late but not much more after that.

> おそいぞ 10時ギリギリか 相変わらずとぼけた奴だぜ




The easiest way to understand any Japanese sentence you're having trouble with
is to try to parse it into its constituent parts first.

> おそい late  
>  ぞ (emphasis/exclamatory particle)  
>  10時ギリギリ just barely 10 o clock  
>  か (rhetorical device)  
>  相変わらず as usual  
>  とぼけた (past tense of とぼける) absent-minded  
>  奴 person (informal)  
>  だ is/are (copula)  
>  ぜ (emphasis/exclamatory particle)

Once you see the parts laid out like that, it's easier to attempt a
translation. Here's a kind of loose translation of it (since I prefer 意訳 to
直訳).

> Hurry up! You've just barely made it by 10 o clock, huh? As usual you're
> such a scatterbrain!
