Someone who purposefully infects you with HIV but doesn't tell you. Therefore, you go around infecting all these other bimbos without knowing you've given them the gift of HIV.
The fucking bitch Sarah from work is a giftgiver (and an excellent one at that). How many people have you given the gift to Sarah??? How many other needless victims are out in the world?!? You insane bitch! You know how hard it was for ME to tell my children that papa has the HIV and now my oldest son has to get checked (don't ask...)!!!
