We’ve been using a book called Marine Fishes of South-East Asia to identify the fish we see each day while snorkeling. I think some of the fish names would be excellent to use as insults.
You Purse-Eyed Scad!
You Green-Racked Croaker!
You Splitlevel Pigfish!
You Tailblotch Tubelip!
You Masted Shrimpgoby!
And this one’s really straight to the point – You Gross Stinkfish!
