Derived from the native tongue of Tignish, Prince Edward Island. Weak is a slang term used frequently in sarcasm. Referring to a "Weak Size Fish" would mean a really big fish. It most commonly stands for the Fredericton based musicians called Weak Size Fish, with a few of their members hailing from the town of Tignish, PEI.
