Fast Food (1989)

Auggie and his friend, Drew, are a couple of "perpetual" college students - their school is so sick of them, they're going to let them graduate just to get rid of them. Augie is trying to 'make it big - fast (the proverbial "easy way"), and his latest scheme is to open a burger joint, and to help entice customers, he and Drew develop a very, very, very special sauce. But even though their place seems to be a huge success, there's an odd side effect: the special sauce is actually a sex drug, and that's where the trouble begins.
