To sneek a quick look at another mans cock when he is asleep. Only a man can murk/merk another man. If the murkee wakes or knows of the murk/merk then it is not a murking. The average man is murked 32 times in his life time.
The act of murking is for the murker to achieve a secret sense of empowerment over the murkee. Used by many through history to gain psychological advantage over ones competitor.
It is well documented that David murked/merked Goliath before their epic battle, only to find that Goliath was not so goliath in all departments. This is the key factor in Davids victory.
Used in everyday life to discribe an act of disgracing someone.
(v) "step back and prepare to be murked"
