Screwballs is a hopelessly dated early 80's raunchy comedy, left in the wake of an increasingly liberated society. It no longer qualifies as being raunchy or funny.
The film is about a group of five teenagers who spend their time sexually harassing and sexually assaulting their female peers.
The whole film is an elaborate setup to show boobies. Supposedly it was difficult for teenage boys to find media depicting topless women in the 1980s. In a world where this issue has been thoroughly dealt with, a movie like Screwballs no longer has any purpose.
