The process by which someone talks out of their arse on frequent occasions and spills a bullshit story of such mammoth magnitude and bollocks that is is obvious that what is coming out of his/her mouth is utter cod shit.

A master of such verbal communication and one which uses such oral regularly would be a bumalinguist.
An extreme example using exclamation would be...

Mr X, "I drank 30 pints of a well known strong Belgian beer last night, invented the typewriter and found a cure for cancer, which I appear to have misplaced, whilst having sex with no less than 5 A List Celebrities".

Mr Y, "Smells like BUMALINGUS, tosser."
