Murkulation is the act or art of performing a "murkle". It is very similar to Trolling, but does not necessarily need to be on the Internet.
Acting like a total cock, because you know that everyone else around you is a total cock. It's a form of revenge, just more entertaining.
The assailant, more commonly known as the "murkler", will persistently and repetitively lay an abundance of rude/offensive/waste comments upon one victim.
The idea is to be as insulting as possible to a wasteman or wastegash.
Dude, check out this harsh level of murkulation laid on this wanker.
