look up any word, like plopping:
 
1.
Someone or something that will eat anything, no matter how disgusting or odd it is.

Usually not to be taken seriously.
Friend: Man, what is your dog doing under the table?

Me: Eating something. Don't know what it is though.

Friend: Isn't that an issue?

Me: Nope, he's a hognivore. He'll eat anything.
