To talk complete nonsense, usually in a repetitive manner, or / and for a prolonged period. To spout verbal diarrhoea, usually to an audience of participating idiots. if the word absolute is used predominantly, then this used to accentuate the synonym 'Rhubarb'. Whilst there is no actual word that has an identical meaning, disregarding the association to the plant of the name. Often two words can be used to inflect the same meaning. Examples of this would be 'talking dog shit', 'talking broken biscuits', 'spouting shit' and talking out your 'arse / or ass pipe'
Mick, can you do us all a favour and stop talking rhubarb.

All that guy has done all night is talk absolute rhubarb, he needs to give it a rest.

I went to a party last night, and it was full of undesirables, there was this one guy that just sat there and talked rhubarb all night.

He must have been on drugs, because he didn't stop talking for over 8 hours and not one part of it made the slightest bit of sense - I've never seen someone talk absolute rhubarb like this guy did. It was like an assault on the ears.
