look up any word, like blumpkin:
 
1.
a bluish-green color
"Hey, what's your favorite color?"
"Prown"
"Oh, haven't heard of that, is it like some purplish brown?"
"No, it's a bluish-green, duh!"

2.
To "own" somebody in the style of a pro, especially in an online game.
I love to prown these n00bs.

3.
A facial expression of someone who tries to pretend they are happy, but are actually sad. A prown may happen when one loses a race and everyone is congratulating them, even though they know they've let the team down. It is put together by the words, frown and proud.
Guy1: Hey nice race there Guy2, too bad you came last.
Guy2: *prowns* yeah, I'm glad I ended up doing it.
