A gibsoning is a loud, incoherent, alcohol induced rant that is delivered with venomous intent. The rant often is delivered sometime between midnight and early morning and the victim is often a spurned lover. The rant can take many forms and can even include abstract acts such as keying a cock into the car door of said spurned lover. Often the gibsoning is delivered with such violent intent that even the gibsoner is unaware of his actions due to what is sometimes called Gibson blindside. A condition where rage often rules common sense. Most gibsons are delivered over multiple messages with each more violent than the last. Often the victim is a mega slut, but rarely can be an unsuspecting victim that happens to be in the vicinity at the time of gibsoning. Gibsoning has been known to take the form of cock pictures on the spurned lovers face book page also. Gibsoning is almost always warranted however the severity is often harsher than necessary.
