Slang term for an attacking batsman. A biffer is the opposite of a blocker, being a defending player. In earlier times (particularly pre-World War II) cricketers were either amateur (Gentlemen) or professional (Players). Typically, but not universally, amateurs would be "biffers" and professionals "blockers". The word derives from the slightly archaic transitive verb, "biff" which means "hit". Today, biffers tend to be known as big hitters.
