Translation

Hi. Someoe's real angry with me. I think they think I cheated on them. Could someone tell me what this might mean? I know it's not good. 

Buang man

diay ni !!!

Thank you

 

Translation and why are they mad

Buang man diay (ka)ni = This is crazy!
Why would you think they're mad at you for cheating? Did you actually? This phrase can also be used to joke but I don't know your situation.
