Dissapoint you all night long
The act a ruining a womans night with the lack of enthusiam and the unwillingness of your penis to perform well, if at all, and your fat belly and uncharming parts begin to show. Hence the woman is greatly pissed with unsatisaction and new found hate, yet feels sad she chose you on her own free will
She just asked him to take her home and Jeff said to her," I would dissapoint you all night long", she accepted and he did.
