Morning Water

NOTICE: This word has an abbreviation. It is Mater pronounced Mah-ter, it rhymes with water. Now for the definition.
The shit you drink when you first wake up because your throat is dry as a bone. Morning water tastes like uh-oh stinky 97% of the time. If it tastes good, consider yourself very lucky. Night water is better.

James: Dude that mater tasted actually good this morning.

Sammy: Bruh, can I have some of it!?!??
James: Nien. Go gitcher own morning water biiiiiitttcchhh!
