The arrival of coeducation at St. Paul's in 1971 inspired the verb to scope (a foreclipping and conversion of "telescope") and the derived noun scoper, "one who appreciatively ogles the opposite sex." From this process has arisen an unofficial organization named SCOPERS, a reverse acronym, or bacronym, for "Students Concentrating On the Palatable Extremities of the Reciprocal Sex.
