Something a female figure (i.e Mother,Sister, Step-Sister, Lesbian Friend, and or Wife/Girlfriend) give a male figure for their birthday. It is an act of sucking the "cock" aka the Penis on their birthday. And since its the male figures birthday, they get to have their way with the female figure (i.e rough and tough)
