A shprengel sandwiched in between a hot ember and a bun from McDonalds. The buns almost always have sesame seeds dipped in guacamole. They are attached to the bun by high pressure pneumatic seals. The shprengel contained inside has to be wearing a grey wife beater, with a weird bra underneath. It may also be optionally wearing black and purple etnies shoes. Almost always, this "caca burger" is accompanied by a "peepee burger" of similar or greater size. Upon digesting a caca burger, seek immediate medical help, or else dire consequences will follow.. such as vomiting, anorexia, fear of men in speedos, and chronic death.
"Did you hear what happened to her last summer, she ate one of those caca burgers, and almost died,"
"Those caca burgers are dangerous!!"
