Stan is a surly little kid who's hot-headed and proud of it. He instigates a LOT of fights, and has the power to back up his taunts. So don't make fun of him because he's pink. He'll kick your ass.
This is a weird thought, but whatever...
You know that episode from Friends where Ross wears that pink shirt? And how he gets all defensive, insisting that it's a "faded salmon" colour? This reminds me of that, the description in particular... Nonetheless, this is pretty cool!
