Pony

Pony is a slang term in betting that refers to £25 (or the equivalent in another currency). It is commonly used in UK gambling circles, especially in horse racing and sports betting.

For example, if a bettor says, "I put a pony on that horse," it means they wagered £25 on the selection. Other similar slang terms include "Monkey" (£500) and "Ton" (£100), which are frequently used by high-stakes bettors.
