cock-knocker brown
The act of giving someone a cock-knock ie punching a male in the genitals. However, the perpetrator (recently after defecating) crouches trouser-less over the recipients head. Subsequently, as a result of the blow, the recipient raises their head in pain, burying their nose into the executor's muddy anus.
As Terry drunkenly slept, Derek crouched over him, ready to deliver the cock-knocker brown.
