X-FROSH is a term used to describe first-year college students. It is a combination of the words 'FRESHMAN' and 'x-factor, ' which implies that these students bring something unique and special to their college experience. Sophomores, or SOPH, are second-year college students who have already been through the transition of being an X-FROSH. They are more experienced and knowledgeable about college life and can provide guidance and support to the new students.
