Joubert

To tell an outlandish lie with no factual basis whatsoever usually with the intention to destroying an opponent usually used in connection with an overbearing abusive semi deranged older female in a position of feigned authority. It is believed that this word derives from the word jail bait. It applies though to an older woman not a young girl. The root of the issue is the same though -- a female who is dangerous through deception, deceit, and manipulation. Another theory is that this word derives from an old Amazon word Juuber which meant a very tall, masculine, evil, dangerous woman who kills and eats men and also children. In the deepest jungles, when a man is really upset because at an older woman, he will shout "Juuber." This is considered an obscenity in the Amazon Jungle.
