I talk ABC because I was born in the states and my Chinese is so weak it can't even hold a conversation.

My Chinese is so weak, I speak ABC. I was born in America, not in a Chinese classroom.

I speak ABC because my Chinese is like a broken phone.

I tried to learn Chinese, but I just say 'I speak ABC' and walk away.
