A celebrity that makes little tween girls cry from their douche baggy ways or have an orgasm by making their tween hormones go hump a donkey. Sometimes both. Ex. Robert Pattinson or Justin Bieber Or just an extreme case of doucheness where the douche in question acts like he's the best thing that has ever happened to this world and considers himself a celeb. He gives himself a nickname that is veryyyy lame.
A man that a woman uses for sex when she is between relationships. This man has no future in her life, he is a tweenerweiner.
Scarlett had suffered sexual famine though she pursued a viable mate, she had been celebate for 5 months. She even became revirginated.
