weakfish 

A fish sometimes called a seatrout; found in salt water coastal areas along the Eastern U.S. seaboard. Look sort of like a trout but definately a salt water fish; called weakfish because when hooked and reeling in for a catch, if you tug TOO hard with your fishing line, you can break its' weak jaw, and therefore loose the fish.

Let's go fishing for weaks; (often hear near marinas along the Long Island Sound shore)

Wealfish 

When someone from small beginnings becomes wealthy and shits on the lower class.

When Dom was elected to Parliament he got too big for his boots and became Wealfish.
