Tuna is unavailable within 50 miles of Newcastle, however there is a delicious alternative with a similar name:

"Tunny"

Tunny is often purchased in the "smartprice" or "value" variety by Geordies who love it for the following reasons:

1. It's cheap.
2. It’s fishy.

a phrase chiefly used in northern England.

it is a contracted form of "it'll be reet", where "reet" means "alright" or "OK".

living your life according to "be reet" is the only way to find happiness in life.

A Tunny is a male or female (whatever they feel like being that morning) that is a natural ginger with cute freckles. Tunnies are usually artists, bronies, and demon possums. Tunnies are a rare breed, and usually only reside in New Mexico, but are also spotted quite frequently on Tumblr.
