From the Dutch 'of Jebber' a mythical city a cross between Bedlam lunatic asylum and the Biblical Tower of Babel whose citizens utter endless streams of mindless senseless babble.
To spout garbage in a manic irrational manner. To gabble.
'She did nothing but Vanjebber all night
'Look at that Vanjebber talking shit again'
From the Folklore of the Netherlands, a person of Jebber. People from Jebber were known for their incomprenhesive and often insane speech.
To be a vanjebber is not only to talk shit but to converse in a low way. People from Jebber are considered to be particularly ignorant, uneducated and of low intellect, and are very often lacivious.
Their speech relects this inherent lack of intellect, education and morals.
that vanjebber has all the wit and charm of a diseased anchovy.
