Incase you didnt realize, we arent all morons.
Most of us who say that realize that they are reffered to as Walleye.

I call them pickeral because it reminds me of back home.

Walleye is to American for me

If you wanna get picky, we could say "walleye" is wrong because the real name is Sander Vitreus.

Walleye is a name for Sand Vitreus, is it wrong? Nope, is Pickeral wrong? Nope.
