Are you driving one of these Douchemobiles around the city; blinding everyone in front of you with your headlights?... You guessed it, might be a douche bag.
If it takes half an hour or 1/2 a jar of pomade to achieve your hairstyle, if every hair on your body, face, and head is waxed into shape... You just might be a douchebag
The height of Douchebaggery: Punctuates every sentence with 'Bra', i.e. "Go with christ Bra!", Arm bracelets, feathers, mullet with bald spot, leather, tons of jewelry and an aversion to sleeves... and then there's the baguette.
