antigenérico 6
It is a neologism that gives rise to different interpretations, the most widespread is the one that qualifies a cultural or artistic work that cannot be pigeonholed in a genre, nor does it pretend to fit into any. But there is also the one that appears in the entry for 'antigeneric' where it is related to an "opposition to generic drugs". Or the one proposed by Mr Ferdinand. See anti- prefix.
