Anger is such a potent creative force I can’t explain myself why no one has come up with a site like this one before: SmellyPoop.com is the way to go if you want to give someone your very worst, namely shit.
The site hosts a very comprehensive gallery of images (some drawn, some actual pictures of human and animal feces, and some realistic shots submitted by clearly very proud makers) which you can transform into an eloquent greeting card, so in a way I think it’s safe to call SmellyPoop the doppelganger of PostSecret. Interestingly, you can learn a thing or two about poop in the whole process of being enraged and communicating that anger (there’s some explanations on color, smell and other such aspects); you can join the forum and share your thoughts on whatever makes you angry or whatever you feel about poop in itself, though note that the general mood is less contemplative than blatantly combatant. Interestingly, everything on this site is open for rating, so that users can rate pictures, videos and comments, so if you want to get a crash course about what the buzz is all about, you’re probably best advised to check out the top rated posts first. The site also features an eCommerce area from where you can buy faux-droppings and calendars depicting excrement from around the world and the species: clearly not too great an idea for that gift you have to buy for your in-laws.
