Omnomivore is a slang term used for something or someone who will eat anything and everything. (Usually spoken as someone is about to consume one or something)
Commonly used by close friends as it may seem silly to say out loud.
"I just called Nicole an omnomivore..."
"You don't even know them, what's wrong with you?"
A funny mispelling, and way of saying the Spanish word "Delicioso."
Mostly used to refer to non edible things in a humorous fashion.
Catie: Hey, that book looks delesoso.
