What is a turkey in bowling?

Answer 1

First Answer:

Second Answer:

A turkey is Bowling lingo for three strikes in a row. Probably, the most famous score for amateur and professional bowlers alike. This is partly due to the fact it has an unusual name, and partly because even a beginner can get one. The term dates back to before the turn of the 20th century. In those years, scoring was much more difficult and to get three strikes in a row was quite an achievement. During Thanksgiving or Christmas week, the proprietor would present a live turkey to the first person on each team who scored three consecutive strikes.
