Mine is O+ !!!
The quality you ask comes mainly from the absence of antigen A or B(antigens determine the blood group) and presence of both A and B antibodies in plasma.
So, what really is happening here is that O can donate to any other blood group because it doesn't have any antigen to trigger antibodies in acceptor body.
But, the catch is it can only receive blood from a group which doesn't have any antigen on its RBC due to the fact that O blood group reacts to both A and B blood group. So O can ONLY recieve from O.
