別人問問題時, 答You got me, 點解?

解：你真係考起我！

正確! I got you 可以解釋為「我明白你的意思」但很少會用 You got me 來說「你明白我的意思」, 多數用 You got it 來表示「你(終於)明白了」

it means: i don't know how to respond
i would go with the first response post
;)

'You got me ' is wrong in both verbal and written English. It should be ' Do you get me? '

Do you get me ? = Do you understand me?
