Phenomenon by which a female is rendered helpless against better judgement concerning a member of the oppoisite sex because of his "fit". The shape/size of the male's penis fits with the female vagina in such a way that even though the male may be repulsive to the female, in personality, looks or social class - the female continues to enlist the male's services because the sex is just too good. This phenomenon may also cause the female to pursue the male - even if her affections are unwanted. Not to be confused with other Cinderella definitions.
Heather put up with Ari's know-it-all attitude and philosophical rants because he had the Cinderella Effect on her.
