coosificarse

An uncommon modern coinage built on cosificar(se) ("to objectify/reify (oneself)"), occasionally used in social-science or feminist writing to describe two people or groups mutually objectifying each other. Rare enough that most native speakers wouldn't recognize it on sight.

• Los personajes terminan coosificándose mutuamente en la trama. — The characters end up mutually objectifying each other in the plot.
• El ensayo describe cómo ambos grupos se coosifican en el discurso mediático. — The essay describes how both groups mutually objectify each other in media discourse.
• Es un término poco usado incluso entre especialistas. — It's a term rarely used even among specialists.

This is a rare neologism, not a word a learner needs — cosificar(se), without the extra co-, is the actual everyday word for 'to objectify (oneself).'
