What objectively douchebag behaviors do you exhibit...

Spinoff from Captain Panic's thread. Let's say you consider yourself a basically non-douchey person. You generally respect the rights of others, you have some basic sense of compassion and a modicum of social intelligence, you don't dye your skin orange or spike your hair, you're not tatted up, and you place your phone on silent in theatres and restaurants.

Are there still one or two chinks in your armor? This is for douche behavior, not behavior which renders you a bad person (cheating on a spouse, stealing from your office, etc). Think popping collars, wearing tinted lenses inside, etc.

I'll start: If the temperature is anywhere between 58 and 80 degrees and it isn't raining, I drive with all windows down blasting my music for all the world to hear. Apparently a total douche move, but I enjoy it.
