satan's asswater
When something smells so bad that you can't take it, such as unwashed and moldy dishes, or a clogged toilet. In order to use such an unwieldy term though, it has to smell like a corpse injected with Iraqi sewage. Reeeally fucking bad.
"That skank's pussy smelled like Satan's asswater."
"I hate Marie's kid. He always smells like Satan's asswater."
"My foot is all swelled up and purple. Not to mention it smells like Satan's asswater...."
