P.S.W.D.B.
P. S. W. D. B. stands for Pucca Shell Wearing Douche-Bag. These guys think they're cool but they're just loud and full of themselves.
My cousin is a P. S. W. D. B. He walks in like he owns the place.
I saw one at the mall wearing a shell necklace and a backwards hat.
My brother's best friend is a P. S. W. D. B. He sings karaoke like it's his job.
