If a bowler bowls an unplayable ball at the batsman, it is often described as what sort of a fruity ball?

Question

Answer 1

Jaffa
It's probably reverse humour, like calling a tall person "Shorty" — a delivery like a Jaffa is nothing like bowling an orange. an exceptionally well bowled, practically unplayable delivery, usually but not always from a fast bowler. Taken from the idea that a 'Jaffa' is the best type of Orange.
