Bettina is an overweight girl that Quagmire assigns Brian to pick up for sex in "Tiegs for Two". Using Quagmire's technique of insulting her, Brian manages to score. The next morning, Stewie asks about her, having seen her slipping out of the house and Brian tells him her name. Stewie observes that the name doesn't really fit her and that her name should be "Oof" or "Thud".
