Are Stinky Bitch and Smelly Bastard listed on the Think Dirty app?

I'm working on it! They charge small companies like me, quite a lot, to research the quality of my products (cost is per product). But you can help me out by doing a search for Stinky Bitch and Smelly Bastard. When they get a certain number of searches, they'll do the research at no cost because they see the demand for information on that product.
