poonibrow
The act of inserting one's finger or penis in the anus of another, then rubbing the aforementioned digit in between the eyebrows, thus creating a unibrow made of poo. Basically a dirty sanchez except further north.
Historians believe that the first recipient of the poonibrow was actually Frida Kahlo but nobody even noticed.
