A massive store. (Could be grocery store, clothing store, etc.)
Did you see Nike's new monstore at the mall today?

If you want our sales to increase, we're going to need to upgrade our shop to a monstore!

Get the Monstore mug.
A monster who is your mentor. Intuited from Paolo Bacigalupi's books "Ship Breaker" and "The Drowned Cities," which feature a mutant named Tool who is monstrous yet also acts as a mentor for some younger characters.
In "Ship Breaker," the mutant Tool gives advice to Nailer, acting as his monster mentor, or monstor.
