Girls that are a part of a blow job 'twinage' lose many of their past friends. Throughout their school they will be known as whores even by the grade 12s who have nothing to do with them. When someone mentions one of the twins, the other comes up soon after aswell.
Blow Job Twins have also been known to finger one another when together. No boy in his right mind would want to date a girl that is part of a blow job twin.
Guy: Hey did you hear about Talen and Jessica ?
