look up any word, like spook:
A person who eats fish but no other kinds of meat. Commonly referred to as "vegetarian".
"Yeah, I'm a vegetarian, but I eat fish." "Well, then you're not a vegetarian." "What am I, then?" "Officially, you're a lacto-ovo-vega-vegavore. But you can call yourself a pescaterian." "Terrific!"
