A girl who sucks a mean dick. A girl who gives a lot of dudes head or "dome".
Damn that chick sucked my dick and two days later sucked Tyler's. She's gotta be a dome donor.

When you get head while giving blood
When Sammy went to donate blood at the blood drive, the nurse gave him donor dome. He nutted in the test tube.
