look up any word, like mexican microwave:

Fairly attractive actress best known for her role on the OC. The only other place I've seen her was in The Sixth Sense. She's the dead girl that got killed by her mother. Word is she has an eating disorder, and ironically, her first appearance in The Sixth Sense shows her scaring the crap out of Cole Sear due to the green stuff pouring from her mouth.
I was watching The Sixth Sense and my buddy was like, "Dude, that's Mischa Barton! Wait, is it? Yeah!" Then I said, "Yeah, she's on The O.C.! Sweet!"

Well, that my friends is Mischa Barton!
Riley: So, what does your new girlfriend look like?
Michael: No word of a lie - she's in the Mischa Barton league!
Riley: Seriously? You lucky f**ker!

Ugly.
(extended because UD needs to have at least 3 words: Mischa Barton is pale, skinny and lacks any real sex appeal to any form of life with a spinal column. Probably attractive to moluscs though.)
"Argh, I just saw Mischa Barton on The OC." "Quick, to the bathroom, we have eye-soap."
