look up any word, like pussy:
 
1.
A mix between a lobster and a crab. Many restaurants are starting to use this term to describe...well lobster and crab unified in a dish, soup or other restaurant-type lingo.
JIM: Hey what do you get when you mix a lobster and a crab together?

Charlene: A Crobster! Oh Jim, so young and naive.
