Neville's broken nose

No: HPFGUIDX 79649

In the battle scene in OOP, after Neville's nose gets broken and he 
is taunted by Bellatrix about his parents, he screams "I DOE YOU HAB" 
at her.   

I have always interpreted this as "I DO YOU HARM", but I recently got 
to thinking about it, and it seems a grammatically and syntactically 
*odd* thing to say.  

Are there any other thoughts or interpretations as to what Neville 
meant to say?
