Try chucking a few mid size carp into a 40 gallon drum and filling it about 2/3 with water. Leave a gaseous area above the water and put the lid on. Secure the lid. Swish it about once a month by taking the top and swirling the drum. In a few months, after allowing it to brew good and proper, tap it, into a watering can, and dilute it about 10/1 parts water/carp brew.

Don't splash yourself, it is a smell you will never forget.
