a senior student who leads events during frosh week.
Type: 5. Frequency — The OED-3 (s.v. "frosh" n.2) and COD-2 (s.v. "frosh") mark the term frosh as "N. Amer. slang" and describe it as a "modified shortening of 'freshman'", possibly from the German word for frog, frosch. Frosh leader applies the general meaning of 'frosh' to a person, usually a more senior student, who facilitates events during frosh week. Frosh leader is virtually restricted to Canada (see Chart 1).
