Liblish is a portmanteau of 'liberal' and 'english'. It is a language used by liberals, derived from english, but with all the words redefined, particularly to attack anyone who offends their sensibilities.
Dina posted her liblish word of the day, which was a bizarre redefinition of the word 'defund'. It's really problematic that she and her friends insist on using liblish definitions when we really should stick with generally accepted english definitions!
