O+
Found out in the Army. It's on your dog tags
The red cross calls me allllll the time. Then if I go to donate, I never weigh enough for my height and they make me leave. Thanks guys. (They're also the WORST I'VE EVER HAD AT DRAWING BLOOD OMFG)
I think my whole family is O+ or O- (I think my dad is - and my mom is +, but I could have that backwards.
I'm not a universal donor, because I'm +, but O is in enough demand they call al the time. Though lately I've been getting too many tattoo's to be allowed to donate.
