We all know people who for whatever reason annoy the shit out of us.
Here are a few types I can think of offhand, please feel free to add more.
The Bicyclist - they wear those gay looking outfits and helmets and think they own the road and refuse to get out of the ****ing way. I love to see people rolling coal on them.
The Vegan - they have superior eating habits and aren't afraid to mention it while belittling your dietary choices. They also have the pallor of a mushroom.
The Engineer - Autists who can't go for more than 5 minutes without mentioning they are an engineer. Very little self awareness or sense of humor.
