I am a big fan of HOF fisherman Joe Bucher. A catch phrase of his is – Its a pig, a hog, a cow, a horse. Its a slab – a super slab. Thus my biggest are reffered too as “super slab’s”
Several years ago I lost it watching two guys boat a big musky on tv with my kid. The one doing the netting started out the name calling by saying that the fish was a “real pig”, but immediately followed that up with “that fish is a horse!” My kid thought the guy was nuts for not knowing the difference between a fish and a horse. I’ve simply used “Dandy” to describe big fish.
