You know what really pisses me off? The idea of people spending something like $80 on a pair of "designer" clothing. Seriously, what the fuck is wrong with some people? Why the fuck would you spend that much on a single item of clothing?
I can understand spending that much on a coat or some heavy duty name brand shoes, but I see places that will charge that much or more for a t-shirt. Higher quality can only account for a certain amount of that ridiculous price, and after that it's just "Ooh, I have a shirt with X's name slapped on the tag. Look at meeeee." That can be pretty irritating.
Something that annoyed me: I went outside to get in my car when I saw a drink sitting on the hood. Since it's really, really fucking unlikely that a stranger strolled through the neighborhood, came up the driveway, and randomly chose to set a drink there, I'm going to assume it's the work of one of the folks living upstairs. Everyone up there knows that's my car. We all know each other, they know I park there, and yet one of them chose to leave the drink there. Normally I wouldn't be annoyed, but upon closer inspection I noticed disgusting purple slushie goop spilled on my car as well. It sounds like someone living up there really needs to start acting like an adult, and that includes informing me of such an accident like that so I can clean it up. I wouldn't be angry at all if the person came and told me what happened, but to lazily ignore the whole thing is pretty immature.
