marmitan 

An adjective used to describe something that is either pleasantly wonderful or absolutely horrid, depending on the user.

You: This shot tastes like garbage liquid, how could anybody possibly enjoy this?
Your snobby coffee friend: My friend, espresso is a luxury of inherent marmitan nature. If you do not like it, something is wrong with you.

"You either love it or hate it." -Marmite
