Cambridge Dictionary: New entries

English language experts and enthusiasts know that new words keep on enering dictionaries. 

According to a recent news report, Cambridge Dictionary has added two new words: 'tradwife' and 'skibidi'. 

The word 'tradwife' seems to have precise and clear meaning. 

But 'skibidi' has diametrically opposite (or contradictory) meanings; it can also be used without meaning anything. I don't really understand why such words are included in the dictionary. I think that Cambridge Dictionary is losing it's authenticity and reliability due to such entries. 

I think that Cambridge Dictionary and other Dictionaries should not succumb to popular demand and should not include words with contradictory meanings and words that don't mean anything.
