A refinement and abstraction of the more lowbrow colloquialismnetflix and chill. Some members of society have access to only a single streaming service, for example cbs all access. In those instances netflix and chill is not applicable to the situation. By using the higher level abstraction "stream and cream" you can make clear your intent without having to specify a particular streaming service. In this way, if I have a partner over I can correctly use the phrase "stream and cream" to denote that I was watching star trek discovery on cbs all access, engaging in coitus, and eventually (or immediately) engage in an orgasmic experience.
Person 1: Hey you took chem last semester right?
Person 2: yeah, why?
Person 1: Can you teach me how to solve titrations?
Person 2: nah bro, I totally did a cram and scram for that class
