Final answer:
In European schools, the crowd known as 'jocks' would probably not be found, as the term and its associated cultural significance are unique to American schools.
Step-by-step explanation:
The type of crowd that would probably not be found in European schools is jocks. The term "jock" is primarily an American term used to describe high school or college athletes, and it is not commonly used within the European schooling vernacular. European schools do have athletes and sporty students, but the unique social grouping and cultural significance attributed to 'jocks' in American schools are typically not present or are manifest differently within European educational institutions.
