Have always loved it  -  and now I just learned the term.  Any ladies in LA (ideally the San Fernando Valley, but surrounding areas are cool) who are serious grool girls?  PM me , please.

It does seem intriguing.

Here's the UD on it:

But I shouldn't have kept reading. One of the other definitions from UD:

"any fleshy part of meat or poultry that is considered refuse, or undesirable to be eaten. it consists of tendons, ligaments, fat, and sometimes veins.

people who continue to indulge into the grool part of the meat fall into the category of MEAF
How am I supposed to eat this steak? It's more grool than actual meat!"
